Characteristics
Permanent magnet motors are today regarded as an interesting solution for a wide range of inverter-fed variable-speed drives. The generally increased interest in these motors have led to many investigations on their feasibility for vehicle propulsion. Consequently, the most important advantages that are expected in comparison to the state-of-the-art asynchronous motors are lower losses and a higher torque density.
The permanent magnet synchronous motor uses permanent magnets to provide excitation, which makes the motor structure simpler, reduces the processing and assembly costs, and saves the slip ring and brush that are prone to problems, which improves the reliability of the motor operation; and because there is no need for excitation Electric current, no excitation loss, improve the efficiency and power density of the motor.
The permanent magnet synchronous motor is composed of stator, rotor and end cover. The stator is basically the same as an ordinary induction motor, and uses a laminated structure to reduce the iron loss when the motor is running. The rotor can be made solid or laminated. The armature winding can adopt concentrated full-pitch windings, distributed short-pitch windings and unconventional windings.
Application
Permanent magnet motors are widely used in the textile industry, petroleum, mining, aerospace, equipment manufacturing, consumer goods, automotive, etc. For example Truck Chassis Fixing Motor,ATV Motor,Winch Motor,Chainsaw Motor,Lawn Mower Motor,Food Garbage Disposal.
