VARIODRIVE Compact VDC-3-49.15 - from 0 to 100 watts in 5.2 centimetres When high output is required but only limited installation space is available, power density is the most important keyword. Therefore, an optimum ratio of rated output and size was one of the most important factors in developing the new VARIODRIVE Compact motor VDC-3-49.15. The performance data of both motor designs (nominal voltage 48 or 24 VDC) speak for themselves. With a diameter of 63 mm and a length of just 52 mm, both versions are substantially shorter than comparable Internal rotor motors. At a nominal speed of 4,000 rpm each, they attain a rated torque of 250 mNm or 150 mNm. The high overload capacity allows start-up torques that are twice that high. At a current draw of 2.9 A (48 V) and 3.5 A (24 V), the drives have a continuous output of 105 W and 63 W, respectively. In addition to the performance data, the internal values of this motor also speak for themselves. With the integrated electronics with powerful DSP, this motor features field-oriented activation via sinus commutation. Thus the attainable speed control range goes all the way down to standstill with holding torque. An additional input for set value allows control of the speed as well as the current, and thus the motor torque. This opens up a wide range of additional application options.
