MOTOR HOOK-UP INFORMATION Due to the fact that many Rotron Products are still operational many years after manufacture and may be reused in other applications, the following information is provided to assure that units are properly re-connected to the electrical supply. Motor Series Number Each type of Rotron motor carries its own series number (not to be confused with the motor serial number) which identifies its electrical characteristics and is found in the type charts on all Rotron catalog sheets describing fans and blowers. Hook-up Identified by Symbol Letter Motor series numbers consist of 2, 3, or 4 digits followed by two suffixing letter or numbers (e.g. 94AF, 295JF). The first letter corresponds to the symbol found in the first column of the chart on the following pages. It identifies the proper hookup diagram. The second suffixing letter F or H denotes insulation class. Definition of Motor Rotation Standard motor rotation is determined by viewing the lead-wire or terminal block end of motor. Wiring is dependent on motor rotation only. If the motor series number denotes other than a standard motor (e.g. 94AF or 295JF) refer to either the Rotron or customer’s specification and/or outline drawing. Electrical Connectors A number of Rotron products are offered with provision for MS connectors as well as our standard terminal block configurations. It is often feasible to incorporate the MS connector on products not now designed for them. It is recommended that catalog offerings be used where possible to avoid delay and added cost and that Rotron be consulted on particular connector model types to maximize standardization with its procurement and inventory advantages. Capacitors The function of the capacitor is to provide a leading time phase shift of the alternating current supplied to the second phase winding of P.S.C. motors to create the required rotating magnetic field which produces motor torque. It is Rotron policy to specify the required capacitance values but not to supply them since field conditions and mounting configurations are variable over which Rotron has no control. Wet or dry dielectric types are available and their AC ratings are specified by the capacitor manufacturers. Rotron capacitor voltage ratings take into account the normal motor supply voltage tolerances of ±10%. The tolerances on capacitance values should not exceed ±10%. Special tolerance limits tighter than these will be noted in individual cases when necessary. Typical MIL specs applying to motor capacitors are MIL-C-25, MIL-C-55514, MIL-C-39022 and MIL-C-19978.

Terminal Coding Motors with lead wires are coded either by color or by markers on the individual leads. Diagrams give both types of coding. For motors with terminal blocks, note the view or view of the terminal blocks in the chart immediately at the right of the applicable hook-up diagram. Select the view which corresponds to the type of terminal block found on the particular motor. Then note the location of the colored coding dot on the view as well as on the motor. From this location the exact position of each of the terminals can be ascertained. Motors with terminal boxes have terminals numbered and color coded. Lead wires may be coded by colors, numbers, or both. Colors may be solid or tracers.
