A torque motor that cannot perform a complete rotation is known as a limited angle torque motor. Brushless torque motors are available; elimination of commutators and brushes allows higher speed operation.
A torque motor that cannot achieve a complete rotation is referred to as a limited angle torque motor. Brushless torque motors are available; the removal of commutators and brushes enables higher speed operation, which is similar to the concept of high-speed brushless DC motors.
