Dunkermotoren compact BG32 DC servo motor

The compact BG32 DC servo motor from Dunkermotoren has an outer diameter of 32 mm and a nominal output power of 10 or 20 W and is related to the BG 42 in terms of technology.

With a modular system of control electronics, encoder systems, brakes and gearboxes matched to the motors, a suitable solution for almost all applications can be found.

A flat speed-torque curve and a good power per volume ratio result in a nominal torque of 2.6 or 4.5 Ncm at a nominal speed of 3500 rpm. Standard motor commutation is via integrated hall sensors.

High-resolution encoders can be attached. Integrated and external electronics are available. Motor version BG 32 KI (2-wire) has integrated control electronics. The functions are short-circuit braking, CW or CCW operation. If only speed control is required for an application, the external electronics BGE 3004A one quadrant controller is available.

Control electronics BGE 3508 is a four-quadrant positioning control with integrated power stage and interfaces for stand-alone operation. Digital or analog in/outputs control the electronics. Alternatively, it can be operated as slave in a CANopen network with device profile DSP 402, protocol DS 301.

Protective functions like low-voltage protection, high-temperature protection and locked-rotor protection ensure high operational safety.

Planetary gearboxes PLG 32/PLG 32 H and PLG 42 S/PLG 42 K are suitable for fitting to the motor. The PLG 32 H has low noise through a helical first-stage gearbox.

For one-, two- or three-stage gearboxes, there are up to 18 different ratios between 4.5:1 and 575:1. Ball bearings with covers on both sides and with lifetime lubrication guarantee long lifetime and maintenance-free operation.

A system of two ball bearings supports high radial and axial loads on the output shaft. For use in harsh environments, the gearboxes are protected against dust, dirt and liquids according to IP52.

High-resolution encoders and brakes complete the modular system. For high requirements regarding control or positioning, the motors can be equipped with digital encoders. Incremental encoder RE 30 generates two square wave signals, shifted by 90° and optionally a reference pulse. Up to 512 increments per channel are possible.

A power-off brake, type E 38, with a braking torque of 20 Ncm can also be attached.
