Ultra-compact brushless DC motor

14 February 2017

The Dunkermotoren ultra-compact BGA 22 Ironless brushless DC motor is now available with a suitable 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 this new motor, there is a four quadrant controller, BGE 6005 with CANopen interface which can supply currents up to 5A. Furthermore, the RE22 encoder is offered with a choice of 256 ppr or 360 ppr and is sized to match the existing BGA 22 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 1.5Nm.

Measuring just 22mm in diameter and weighing only 63 grams the BGA 22 3-phase brushless DC motors 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 ideally suited to medical, pharmaceutical or aviation motion control applications. For example, powering small pumps in micro-fluidic handling systems, or wherever optimum flexibility or up-scaling is required.

In common with their existing brushless direct current motors the BGA 22 is designed for exceptional long life, high power density and efficiency, high dynamic acceleration and low noise levels. It features Neodymium magnets, with no cogging torque, coreless design with integral
hall sensors for rotor position detection.
