KD and DR Motors are of very thin design. By combining the motor with the gears in the modular system, any speed can be set and high torque can be generated in a small cross-section. Combinations with brakes are also possible. A temperature switch for thermal motor monitoring can be integrated into the motor. The motor can run on 50Hz power supply and 60Hz power supply. Different 230V phase voltages can be designed. Versions that meet higher IP requirements and do not have blowers are also possible. The length and diameter of the output shaft can be varied if desired.
