TORQUE
MOTORS
BT SERIES

Technical specifications

BT torque motors are multipole electric servomotors consisting of two main components, a rotor
ring and a stator ring, and are designed to provide very high torque. They are used in all applications where the use of standard motors connected to a gearbox does not allow high productivity standards to be achieved and allow the reduction of machine costs related to maintenance and energy consumption.

By being fully integrated into the machine body, BT torque motors offer the enormous advantage of
eliminating mechanical parts of the machine and consequently a lower possibility of breakdowns,
combined with a lower management of spare parts.
