Creating New Value
The bicycle was an icon of Korea in the 1970's. The populations usage of the bicycle as a daily mode of transportation rapidly grew through this period.In 1972, DYNAMEC effectively answered the market’s needs by starting the first steps as a manufacturer of bicycle components including chains, brake assemblies, and hubs.
From 1979, technical experience and reputation gained from the bicycle business, expanded DYNAMEC criteria into supplying engine bearing caps and caliper pistons for the automotive industry. With specialized production lines and consistent quality management, sales of automobile parts gradually increased.
History
Professional engineering at DYNAMEC ensures the highest and stringent methods for improved applications.
In 1991, DYNAMEC introduced cold forged bevel fears to the
domestic Korean market for the first time and drew
large customer notice as a
reliable partner.
In 1997, DYNAMEC successfully paved its way to
secure the position as a global supplier by establishing the Tianjin,
China manufacturing facility.
This facility became DYNAMEC’s outpost to respond to various customers’ needs, including Samsung Electronics, seeking local partners in the Chinese market. The “challenge” has been our drive and motivation to be a global supplier for worldwide industrial market needs.
06 07DYNAMEC
DYNAMEC has always aimed to advance technical improvements and organizational management system to strive at being a professional manufacturer of industrial components.
In 1985, DYNAMEC began supplying VCR head drums to SAMSUNG which led to manufacturing opportunities for JVC, Toshiba, renowned global VCR manufacturers. Starting in 1986, a new facility for starter motor solenoid switches
allowed DYNAMEC
production and manufacturing
technical experience to accumulate, which
would later be applied to the automotive industry.
In the late 80’s DYNAMEC continued to innovate in manufacturing methods and process design by opening an R&D Center to accomplish advanced precision forging technologies.

Electric Components & Motors
DYNAMEC has the full capabilities to offer our customers the entire electronic manufacturing process- from coil preassembly to end-of-line testing. Our quality principles apply here as well; all under one roof. As a system integrator, we control e-motor assembly and ensure top quality procedures, processes, and products. The moving part in an electric motor is known as the rotor which
turns the shaft to deliver the mechanical power. The rotor usually has conductors laid into it which carry currents that interact with the magnetic field of the stator to generate the forces that turn the shaft. However, some rotors carry permanent magnets and the stator holds the conductors.
The stator is the stationary part of the motor’s electromagnetic circuit and usually consists of either windings or permanent magnets. The stator core is made up of many thin metal sheets, called laminations. Laminations are used to reduce energy losses that would result if a solid core were used.
Electric machines come in two basic magnet field pole configurations: salientpole machine and nonsalient-pole machine. In the salient-pole machine the pole's magnetic field is produced by a winding wound around the pole below the pole face. In the nonsalient-pole, or distributed field, or round-rotor, machine, the winding is distributed in pole face slots.
A commutator is a mechanism used to switch the input of most DC machines and certain AC machines consisting of slip ring segments insulated from each other and from the electric motor's shaft. The motor's armature current is supplied through the stationary brushes in contact with the revolving commutator, which causes required current reversal and applies power to the machine in an optimal manner as the rotor rotates from pole to pole.
