The epm-papst VDC-3-49.15-K4 motor is a three-phase EC drive with a multi-pole magnetised neodymium magnet. The device is available now from RS Components. The electronically commuted external-rotor motor has an extremely high power density and a compact design. Excellent control action is obtained due to the field-orientated control with sinus commutation. The device has fully integrated control electronics with high-performance DSP and extensive interfaces. This allows particularly flexible control of the drive and the drive can consequently be adapted to different applications. The integrated temperature cut-out gives reliable protection against overload.


The ECI-63.20-K4, 63.40-K4 and 63.60-K4 motors are EC drives. The Series ECI electronically commutated internal rotor motors excel with large power density and dynamic performance. The modular system provides fully integrated class 4 control electronics with various analog and digital interfaces. These can be parameterised via an RS485 interface. This allows particularly flexible control of the drive and the drive can be adapted to different applications.


Nominal outputs from 150W to 400W with corresponding packet lengths from 20mm to 60mm are available. The company uses the designation 'K class' to describe the functional scope of their motor systems. The higher the digit the greater the functional scope. Of the planned classes 1 – 6, to date classes K1, K4 and K5 are in use.
