Ultra-compact brushless dc motor with gearbox and controller

03 April 2017

The Dunkermotoren ultra-compact BGA 22 Ironless brushless DC motor is now available with a gearbox, encoder and controller. This BGA 22x22 dCore option benefits from the innovative ironless, BGA axial flow design and provides users with advantages such as zero-cogging torque, low vibration and very low audible noise.

In addition to the new motor, there is a four quadrant controller with CANopen interface which can supply currents up to 5A. Furthermore, the encoder is offered with a choice of 256 ppr or 360 ppr and is sized to match the existing motor diameter for ease of mounting.

For simple applications, Dunkermotoren offer the BGA 22 dGo version with integrated electronics and functions such as change of direction, start/stop, speed set input and speed output signal. The PLG 22 and PLG 24 are the two planetary gearboxes offered which provide a nominal torque of up to 1.5 Nm.

Measuring just 22mm in diameter and weighing 63 grams the BGA 22 3-phase brushless DC motors are said to deliver exceptional power to size and weight ratio, producing up to 50% more power than comparably sized brushless DC motors and are ideal for low noise applications.

They support low nominal speed (around 3,000 rpm) and are suited to medical, pharmaceutical or aviation motion control applications.
