A new ultra-compact brushless DC motor measuring just 22mm in diameter, weighing only 63g and which delivers exceptional power to size and weight ratio, has been added to the established range of brushless DC motors available from Dunkermotoren.

The 3-phase brushless DC BGA 22 motor (axial magnetic flux, 8 to 22W) produces up to 50 per cent more power than comparably sized brushless DC motors, and will be appreciated in low-noise applications, especially when used in conjunction with a gearbox.

Dunkermotoren’s BGA 22 supports low nominal speed (around 3000rpm) and is 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 Dunkermotoren’s existing brushless direct current motors, the BGA 22 is designed for long life, high power density and efficiency, high dynamic acceleration and low noise levels. It features Neodymium magnets, a no cogging torque, coreless design with integral hall sensors for rotor position detection.
