Permanent Magnet Motors

Harness the Power of PM Motors – a Custom Magnet Application by Bunting.

Custom Magnets and Magnet Applications for Permanent Magnet Motors

Bunting provides customers with a diverse range of custom magnets for permanent magnet motors (PM motors) to drive a variety of applications. So many of the things essential in our lives—our cars, our home appliances, and the industrial equipment we rely on to live a modern lifestyle—depend on motors as their key components. Bunting helps our customers to build the best motors for their applications. Our team of expert engineers works with clients from project inception all the way to completion.

The most common type of PM motors is brushless DC electric motors (BLDC) that utilize permanent magnets as opposed to a winding, which requires an electric current to generate the field. Since no electrical current is required for the rotor field, the results are major energy savings and efficiency improvement compared to induction-type motors. Permanent magnet motors have many overall benefits, including:

• Steady Magnetic Field: Permanent magnet motors generate a consistent, steady magnetic field in comparison to standard synchronous motors.
• Environmentally Friendly: PM motors allow for high efficiency, oil-free operation free of emissions. They allow less environmentally friendly equipment, such as fossil generators, to be avoided. The amount of energy required to create these motors is insignificant compared to how much electromagnetic energy they are able to ultimately produce. Permanent magnet motors are on the frontline of the ongoing development of green energy applications.
• Size: Permanent magnets are lightweight and compact, meaning they require decreased installation space while maintaining high power.
• Torque: Compared to standard synchronous motors, PM motors display a significant improvement in torque.
• Temperature: PM motors generally operate at lower temperatures compared to other motors, yet deliver improved drive and performance.
• Investment: PM motors are dependable, durable, and affordable.
• Applications: Automobile accessory motors, robotics, factory automation, air conditioners, computer disc drives, hot blowers, appliances, etc.
