Frameless Brushless DC Limited Angle Toroidal Motors

The TD motors are used in applications that require limited angle rotation with a constant torque throughout the excursion angle.

刘玥首次大战黑人toroidal motors have the dual advantage of being brushless and providing constant, ripple-free torque sustained through the required angle. Eliminating the slot cogging effect makes toroidal designs desirable in many applications, especially in incremental motion systems and in the field of control instrumentation. In addition, lower rotor inertia motors may be substituted where a high mechanical time constant was incorporated to filter torque ripple.

The motors are supplied as a direct drive rotor / stator frameless part set that is directly attached to the load. This form of attachment eliminates backlash and increases servo stiffness for an optimized direct drive system.

The TD motors consists of a wide range of sizes, outside diameters from 0.6 to over 5 inches (15.24 to 127 mm).
