AC Torque Motor

Product Description

An electric motor with accurate torque control is referred to as an AC torque motor, sometimes known as an AC torque motor or a torque synchronous motor. Contrary to normal induction motors, AC torque motors are designed for high torque at low speeds and are frequently used in positioning, machine tools, and robotics applications that demand precise and reliable torque production.

The following are some essential qualities and traits of AC torque motors:

1. Design: Low-pole-count AC torque motors typically have a lot of magnetic poles in the stator and little rotor inertia. High torque can be generated using this arrangement, even at slow speeds.

2. Synchronous Operation: When an AC torque motor is operating in synchronous mode, the rotor and the stator's spinning magnetic field rotate at the same pace. This synchronous operation avoids the slip that is found in induction motors and enables exact control of torque output.

3. High Torque Density: AC torque motors are renowned for their high torque density, which refers to their ability to produce a substantial amount of torque for their size and weight. They are thus appropriate for situations requiring strong torque but little space.

4. AC torque motors have the capacity to operate in direct drive topologies, which eliminates the need for extra mechanical parts like gears or belts. Increased economy, decreased backlash, and better precision are all benefits of direct drive systems.

5. AC torque motors are exceptional in producing great torque at low speeds. Applications that require precise control of force and position, such robotic arms, CNC machines, and automated manufacturing systems, benefit from this property.

6. Control Options: A number of techniques, such as vector control, field-oriented control (FOC), and direct torque control (DTC), can be used to regulate the torque of AC motors. These control methods provide accurate modulation of speed and torque as well as dynamic response.

The advantages of AC torque motors include high torque precision, superior torque control at low speeds, and the capacity to do away with mechanical parts like gearboxes, which leads to less maintenance and increased system effectiveness.

To optimise their performance and provide the appropriate torque control characteristics, AC torque motors may need specialised drive electronics and control algorithms.

In general, AC torque motors are created especially for uses that call for high precision and high torque control at low speeds. In robotics, machine tools, automation systems, and other fields where precise force and position control are essential, they are frequently utilised.
