PSM - Permanent Magnet Synchronous Motors

High Performance Combined with Efficiency

Thanks to the use of permanently magnetic materials, permanent magnet synchronous motors, also called “permanently excited synchronous motors” or “regulated synchronous motors”, enable extremely high levels of utilisation and efficiency (especially in the partial-load range) to be employed.

Very Slender Motors

The excellent performance factors of PSMs significantly reduce power requirements and allow the size of the inverter to be minimised. Extremely slender motors can be achieved with permanent magnets. The rotors remain markedly cooler than is the case with asynchronous motors as rotor losses are much lower. In addition, multi-polar motors are capable of extreme overloads.

Areas of Application: Dynamics and Good Utilisation

SERVAX recommends the use of permanent magnet synchronous motors where stringent demands are placed on utilisation (with regard to space), dynamic capabilities (overload), speed control range and efficiency. These motors can also be used economically where space restrictions are not an issue.
