BLDC drives

No need for Hall sensors

With integrated bus systems and STO, the Romotion 84 BLDC drives aim to deliver energy efficiency, performance-to-size ratios, and multiple connectivity capabilities. At the heart of it is one of Rotek’s three-phase synchronous motors.

The integrated control electronics with Smart Drive Technology allows for sensor-less commutation operation by eliminating the need for the otherwise necessary Hall sensors. As serial interfaces Modbus RTU and EIA-485 are available, but optionally also CANopen. Additionally the motor has three digital I/Os.

The drives’ speed setting has a range of 0 V to 10 V (optional 0 V to 24 V). A nominal voltage of 24 VDC or 48 VDC, an output from 80 W to 200 W, and a nominal speed of 3100 min-1 or 3200 min-1 are enabled. The speed control ranges from 400 min-1 to 4000 min-1 and the nominal torque is available with 0,34 Nm or 0,39 Nm. The motors have IP40 protection class, with IP54 and IP55 optionally available. The permitted ambient temperature is 0 °C to +40 °C.

About Rotek

In 2000, the Treusch family founded Rotek in Germany and took over Hasselbach and Kausch Elektrokleinmotoren. Paul Hasselbach had been producing a range of synchronous motors and drives since 1984. Rotek focuses on the development of small motors. In 2008, production started on Rosync motors with Green Drive technology.
