Brushless DC (BLDC) Motors for High Performance and Rugged Reliability

Sensata specializes in designing brushless DC (BLDC) motors to customer specifications, delivering the best solution for application requirements. These unique motor designs enable users to enhance the motion system by using decades of knowledge and proprietary magnetic design tools.

Sensata provides the following bespoke Brushless DC motor configuration options:

Frameless BLDC Motors

BEI Kimco’s frameless motor part set design means that the motor can be fully integrated within the customer assembly, which results in the highest ratio of torque to volume. In this configuration, the motor’s rotor and stator are housed within the customer’s “next higher” assembly utilizing a common shaft and bearing system.

This results in increased coupling efficiencies and reduced system size, weight and cost. The high magnetic pole count pancake “Torquer” motor produces seriously low cogging for smooth, low-speed operation and high-accuracy positioning applications.

Features

Permanent magnet rotor design with the highest energy product for better efficiency

Rotor with a high pole count for smooth operation

Magnetic circuit design proprietary for maximum efficiency
