EC servomotor EC06 series

three-phaseDC24 V

EC motors are also called brushless DC motors. Their construction is equivalent to the construction of a three-phase synchronous motor with permanent magnet rotor. There are no service life limited parts (except for ball bearings), like for example the carbon brush for DC motors. However, the control behavior and characteristic curve of EC motors are similar to those of a DC motor. By means of the simple and robust design and the low requirements of control electronics this motor type can be used with a simplified frequency converter with block commutation. On the inside, a polymerbonded neodymium magnet ring is employed. With its compact magnet ring it is particularly suitable for higher torques. Compared to a common asynchronous motor an EC motor is characterized by a higher power density. In combination with a rotor position detection on Hall basis (RLE) it can also be used as variable-speed drive. The EC series of Heidrive GmbH consists of three sizes with different lengths and is covering a power range from 35 W to 220 W. This corresponds to a nominal torque of 0.1 Nm to 0.7 Nm. The motors specified here have a triple overload capacity
