Catalog – CMP40 – CMP112, CMPZ71 – CMPZ100 13
2 Product description2.1 CMP synchronous servomotors
The CMP servomotor series combines high dynamics, high torques, and precision in acompact design.Their innovative design with the latest in winding and magnet technology offers a mo-tor system with optimum dynamics and the best control characteristics at the smallestspace. The cast stator protects the motor against vibrations and humidity.Characteristics of SEW-EURODRIVE synchronous servomotors:
• Static torque from 0.5 to 95 Nm
• High dynamics (ratio between rated torque and mass moment of inertia of the mo-tor)
• High degree of protection (IP65)
• Robust encoder system (resolver)
• The optimal encoder system with sine/cosine encoder allows for a very wide settingrange and absolute position detection,
• High continuous torque at low speeds and at standstill, without forced cooling fan• High overload capability• NeFeB magnets, permanent magnets with high magnetic flux density.CMP motors can be optionally equipped with a holding brake and a forced cooling fan.CMP servomotors can be combined with MOVIDRIVE® inverters and MOVIAXIS® mul-ti-axis servo inverters.
2.2 CMPZ synchronous servomotors – version with additional flywheel massCMPZ synchronous servomotors are equipped with an internal additional flywheelmass. These motors combine high torques and precision in a compact design andprovide particularly favorable control characteristics with high external masses. Fur-thermore, the internal higher moment of inertia allows for a smaller gear ratio.In addition to the above mentioned features of the CMP motors, CMPZ motors are op-tionally available with a powerful BY working brake with high working capacity and op-tional manual brake release.
2.3 Features of CMP. servomotorsSynchronous servomotors with permanent magnets offer highest dynamic overloadcapacity.State-of-the-art winding and magnet technology enable a compact motor system withgreat dynamic qualities, smooth running and excellent control characteristics.

2.3.12 BrakemotorsThe motors can be equipped with an integrated mechanical brake on request.The brake is controlled by a brake controller that is either installed in the inverter orseparately in the control cabinet.
BP brake / BK brake
BP and BK brakes are DC-operated electromagnetic disk brakes. They release electri-cally, and brake using spring force (BP brakes) or magnetic force (BK brakes). Thebrakes are applied automatically if the power fails. This means they meet the basicsafety requirements. The brakes cannot be retrofitted and usually operate withoutbrake rectifier or brake control unit.
BY brake
This is a DC-operated electromagnetic disk brake that is released electrically and ap-plied with spring force. A characteristic feature of this brake is its extremely short de-sign. The brake endshield is a part of both the motor and the brake. The integratedconstruction of the SEW‑EURODRIVE brakemotor permits particularly compact andsturdy solutions.The brake can also be released mechanically if it is equipped with manual brake re-lease. In this case, a lockable hand lever with automatic reset is included in the deliv-ery.The BY brake is also available as safety-rated brake for use in functional safety appli-cations. In this case (FS) is added to the name.

4.2 Circuit breaker and protective equipment4.2.1 Preventive measures
Synchronous servomotors must be protected against overload and short circuit.Install the motors with sufficient space for air to cool them.The surface temperature may be in excess of 100 °C during operation in accordancewith thermal classification F. Therefore, measures to prevent inadvertent contact areessential.The motors are equipped with temperature detection to protect the motor windingagainst overheating.The temperature is measured by temperature sensors KTY 84 to 130 installed asstandard, or, for sizes 71 to 112 by optionally available /TF temperature sensors. Thecorrect model must be activated in the servo inverter to enable thermal motor protec-tion (I2t, effective current monitoring). For information on the procedure, refer to thedocumentation of the servo inverter.
4.2.2 EMC measuresSEW‑EURODRIVE synchronous servomotors are intended as components for instal-lation in machinery and systems. The designer of the machine or system is responsi-ble for complying with EMC Directive 2004/108/EC.
Routing brake cables
Brake and power cables may only be routed together if either the brake cable or thepower cable is shielded. We recommend that you use prefabricated cables (→ 2 341).
Notes on encoder connection
Observe the following notes when connecting an encoder:• Use only a shielded cable with twisted pair conductors.• Connect the shield to the PE potential on both ends over a large surface area.
Thermal motor protection
The cables can only be routed together if either the KTY cable or the power cable isshielded. We recommend that you use prefabricated cables (→ 2 341).

5.3 Thermal characteristics5.3.1 Notes on selecting synchronous servomotors
Project planning for a servomotor involves the following tasks for determining the ther-mal and dynamic load on the motor:
• Calculating the effective operating point for checking the thermal load on the mo-tor.
• Calculating the maximum operating point for determining the motor/inverter com-bination.
• Determining the inertia ratio Jext/JMot for checking the stability of the speed control.
5.3.2 Procedure
• Determining the maximum speed based on aspects of the inertia ratioJext / JMot< 15.
• Maximum required torque Mmax at maximum speed nmax (maximum operatingpoint).
Mmax < Mdyn_Mot when nmax
Mdyn_Mot corresponds to the maximum torque with the specific motor/inverter com-bination. This operating point must lie below the characteristic curve for the maxi-mum torque of the motor/MOVIDRIVE®/MOVIAXIS® motor combination.
• Effective torque demand at the average speed of the application (effective operat-ing point).
Meff < MN_Mot when nmedium
This operating point must lie below the characteristic curve for continuous torqueto ensure thermal stability of the drive.
5.4 Operating temperatures5.4.1 Maximum ambient temperature
CMP motors are designed for use in a temperature range between -20 °C and +40 °C.
5.4.2 Higher operating temperaturesCMP servomotors can optionally be used at a maximum ambient temperature of 60°C.Please contact SEW‑EURODRIVE if the motors are used at higher ambient tempera-tures. See also chapter Derating for increased ambient temperature (→ 2 38).
INFORMATIONIf the motor is operated at higher ambient temperatures, also take account of theproject planning for the power cable.
5.4.3 Cold storage applicationTaking suitable measures, motors can be used for cold storage applications up to-40 °C. The temperature range from -40 °C to +10 °C is listed on the nameplate.

5.5 Derating for increased ambient temperatureFor projecting the CMP synchronous servomotors with permanent-magnet excitation,the following derating applies in the ambient temperature range +40 °C to + 60 °C:• The thermal speed/limit torque characteristic curve is re-scaled towards the origin
(minimized). The thermal operating point based on effective torque and thermallyeffective speed of the application must be below the re-scaled characteristic curve.

5.6.1 Speed classes, rated speedsSpeed classes (rated speeds) of synchronous servomotors:
• 2000 rpm
• 3000 rpm• 4500 rpm• 6000 rpmAs synchronous servomotors operate as controlled drives, it is necessary to considerthe inertia ratio between the load and the motor. This ratio is a decisive factor in deter-mining the quality of closed-loop control. The inertia ratio should not exceed the val-ues listed in the table below.Reduction of the inertia ratio using the motor speed or the selected gear unit reductionratio offers hardly any advantage with respect to closed-loop control starting at the val-ue Jext / JMot < 8.Backlash and elasticity negatively influence the possible dynamic response of thedriveline and must be kept to a minimum.As a result, the maximum speed should be selected such that the following criteria aremet:
Driveline Control characteristics Inertia ratio Jext/ / JMot
Forged gear rack, re-duced backlash gear unit
Low backlash and low elasticitydrive
Jext / JMot < 15
Toothed belt, reducedbacklash gear unit
Common servo applications Jext / JMot < 15
Toothed belt, standardgear unit
Standard applications, cou-plings with torque buffer (elas-ticity)

5.6.3 Applications
High accelerations
The rotor of the CMP synchronous servomotor is designed to be low-inertia. Thesemotors are the optimum choice in very dynamic applications. For high accelerationsand accelerations in the millisecond range, the synchronous servomotor is usually thetechnically and economically best solution.
Additional flywheel mass
The rotor of the CMPZ synchronous servomotor is equipped with an additional fly-wheel mass. This additional flywheel mass allows for handling large external masses.
Cogging
The motors produce small torque ripple due to the servo drive design. This torque rip-ple is corrected by the inverter.

5.8 Project planning exampleIn the example, a gantry with synchronous servomotors is determined.The symbols used in the equations are explained in chapter Drive and gear unit selec-tion data (→ 2 30).
5.8.1 Selecting the x-axis (travel axis)
Gantry with servo drives – travel axis
Reference data:
• Total moved mass: mL = 50 kg
• Diameter of the belt pulley: d0 = 75 mm
• Friction coefficient of the axis: µ = 0.01
• Travel speed: vmax = 2 m/s
• Maximum acceleration/deceleration: amax = 10 m/s2
• Cycle time: tz = 3 s
• Pause time: tp = 1.8 s• Load efficiency: ηL = 0.9• Mounting position of the gear unit: IM = M1For the drive, a PC.C gear unit is designed to be mounted directly to a CMP servomo-tor.The overhung load is to act on the shaft center.Power is transmitted via a belt pulley.
