BLHP Series

Brushless High Performance Servo Series

MTI's Brushless High Performance Servo Series of DC Motors (the BLHP Series) features compact, high power density designs with high torque to inertia ratios, and high operating efficiencies. They are ideal for extra smooth position control, especially where detent torque needs to be minimized. In addition, they are suitable for operation under environmental extremes of temperature, shock and vibration. They are commonly used as servo position control motors onboard aircraft. Generally, they can accommodate the most stringent aerospace and industrial position control applications.
