BLDC Motor with Built-in Speed Controller

By combining the brushless dc motor and speed controller into a single compact, streamline package, GEMS provides this space-saving design that minimizes the wirings and eliminates the motor- driver compatibility issues. These motors with integrated controllers also save on cost over separate motor and controller electronics. Due to the simiplicity of wiring, these driver integrated brushless motors are perfect options for the customers who are looking to replace their brushed motors with brushless ones in their products.

IP65 rated motors are available for the wet and dusty environment. All the motors can be custom designed to match with your power source and the needed rated RPM. A wide range of planetary and spur brushless motor gearboxes can be mounted on GM57BLYI series motors for high torque and low speed applications.

NEMA 23 57mm Brushless DC Motor with Integrated Speed Controller

All models can be custom designed for 12V 24V or 36V power supply, and the rated speed can be designed to be any number between 1000 rpm and 6000 rpm.

A specific design for the power source with voltage fluctuations (eg: a solar panel) is available upon request.
