What Are The Two Main Types Of AC Gear Motors?

The two main types of AC gear motors are synchronous and asynchronous motors. What is the main difference between these two types of gear motors? In this blog, Bauer GMC, a major distributor of gear motors and gear reducers in Mississauga, Ontario, explores the main differences in detail.

What Is A Synchronous AC Gear Motor?

Asynchronous AC gear motor is a motor that operates at one constant speed. It is called a synchronized motor because the speed of the motor matches the frequency of the input power supply. This constant speed is achieved by the inherent design of the gear motor. 

The rotating magnetic field of the stator part of the motor is used to match the rotor’s magnetic field. This creates constant and precise output speed. Due to this feature, synchronous AC gear motors are mostly used in applications requiring low speeds and high torque. 

What Is An Asynchronous AC Gear Motor?

Asynchronous AC gear motors have a setup wherein the rotor speed is slightly slower than the rotating magnetic field of the stator. This phenomenon, also known as slip, helps this gear motor to generate plenty of torque by means of electromagnetic induction. Due to this feature, they are best used in applications where the motor speed is required to be reduced and the torque to be increased. 

Most common examples include conveying systems, fans and pumps, as they are simple, durable and highly cost-effective. 

Conclusion

To conclude, the main difference between synchronous and asynchronous AC gear motors lies in the way the rotor and stator operate with respect to each other. This changes their features and their subsequent applications.

FAQs:

What is the most defining feature of a synchronous AC gear motor?

Synchronous AC gear motors are known for their high efficiency as they consistently convert electrical energy into mechanical energy.

What makes asynchronous AC gear motors cost-effective?

Asynchronous AC gear motors are cost-effective because of their simple design, as the motor operates on electromagnetic induction.
