WebDC motor drives Figure 1: Control loop of a DC motor drive Features – Field orientation via mechanical commutator – Controlling variables are armature current and field current, measured DIRECTLY from the motor – Torque control is direct In a DC motor, the magnetic field is created by the current through the field winding in the stator. WebDC Torque Motors. These low-voltage DC direct drive motors deliver high torque at extremely low speed. They are perfect for applications—such as forward-looking infrared radar (FLIR)—that require simple control, very smooth motion, and maximum rate and position accuracy, while minimizing size, weight, power and response time.
