12v 24v 36v and 48v Brushless (BLDC) Motor Manufacturer

 

GEMS Motor manufactures and supplies NEMA 17 23 34 42 frame and metric size 28mm -130mm brushless motors. All our motors can be custom designed to operate with 12 volt, 24 volt, 36 volt, 48 volt or higher voltage.  GEMS offer different lubricant options and IP65 class motors for extreme temperature, dusty and humid environment. The integrated hall sensors, encoders or resolvers are also available for the application where the accurate position and velocity feedback is required. GEMS Motor also provide a wide range of brushless gear motors and brushless DC motors with integrated driver. Custom dual shaft and mounting flanges are available upon request.

Brushless DC motors also known as BLDC or EC motors, have much longer life span than brushed DC since there are no brushes to wear out. This gives you a better long-term value for your investment. Another main advantage of brushless motors is its high efficiency. Brushless motors are also perfect motors for the application running at high speeds such as power tools and brushless blowers. In many cases, brushless motors are made as multi-poles, eg: 4 poles or 8 poles, which enhances the torque at the cost of speeds. In such applications, an extremely high rpm is not required but a high torque is nice to have. Please check the motor specifications below to get the information about maximum speed and torque capabilities.
