DC 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. These motors provide a servo actuator that can be attached directly to the driven load. A permanent magnet field and a wound armature act together to convert electrical power to torque.

Features
- Ideal for positioning or speed control systems that require high stall torque, high torque at low speed or optimum torque at high speed.
- Frameless and housed models available in a huge range of sizes and torques
- High torque-to-inertia ratio for rapid start/stop and acceleration
- High torque-to-power ratio for low power input requirements
- Low electrical time constant for excellent command response at all operating speeds
- Linear torque response for all input currents and speeds, with no dead spots
- Reliable operation over a long life
- High accuracy even at low speeds, without the backlash and compliance of a geared system
- Smooth, quiet operation
- Compact, adaptable design
- Co-engineered modifications include specific magnet materials, laminations, magnetic pole counts, stack lengths, windings, installation geometry and more
