Dunkermotoren BG75 brushless DC motors

Dunkermotoren BG75 DC motors feature output powers up to 500 W and torques up to 5 Nm. They have sufficient reserves to take on numerous drive tasks in automation. Combined with components selected from a comprehensive package of equipment, the motors can become fully fledged, cost-effective and compact servo drives.

The motors are available with a variety of integrated electronic functions. The spectrum starts with regulation electronics in the SI version, which, besides speed control, also permits defined acceleration and braking operations. The next stage is the PI model. It provides convenient user software for setting the motor parameters for positioning, speed and torque. The CI variant features a DSP402-compliant CANopen interface. This enables modification of the significant parameters for a trajectory ‘on the fly’.

The MI version represents the maximum available, and incorporates a freely programmable motion controller. With it, a DC motor can, independently, execute master-slave functions in a drive network.

A range of carefully adapted components ensures that the brushless BG75 motors are a true alternative to servo drives. These include a magnetic encoder, which provides 4 x 1024 impulses per revolution. It is installed as standard in the PI, CI and MI versions of this motor. Optionally, the absolute encoder AE50 can be fitted; it has a repeatability of 0.3°. With it, highly accurate positioning applications can be realised.

To achieve high torques and low speeds of rotation, there is a wide range of planetary and worm gears that fit the BG75 motors.
