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.
In certain applications, a torque motor with restricted rotational capability is called a limited angle torque motor. High-speed brushless torque motors are also accessible, thanks to the elimination of commutators and brushes, which is relevant in contexts where high-speed operation is necessary.
