3 Product Description
3.1 Description VDC-3-49.15-K4
The VDC-3-49.15-K4 motor is a 3-phase EC drive with a multi-pole magnetised neodymium magnet. The electronically commuted external-
rotor motor has an astonishingly high power density and a compact design. Excellent control action is achieved due to the field-orientated
control with sinus commutation. The VDC-3-49.15-K4 has fully integrated control electronics with high-performance DSP and extensive
interfaces. This enables particularly flexible control of the drive and the drive can therefore be adapted to different applications. The
integrated temperature cut-out provides reliable protection against overload.
Rated wattages from 100 to 150 watt are available to choose from.
3.2 Description of the eCI-63.XX modular system K4
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 ECI-63.XX modular system K4 has fully integrated class 4 control electronics with several
analog and digital interfaces. These can be parameterised via an RS485 interface. This enables particularly flexible control of the drive and
the drive can therefore be adapted to different applications.
Nominal outputs from 150 to 400 W with corresponding packet lengths from 20 to 60 mm are available to choose from.
3.3 Description of the electronic classes
ebm-papst uses the designation “K class” to describe the functional scope of an ebm-papst motor system. 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.
