Paper Mill Permanent Magnet Synchronous Motor
A permanent magnet synchronous motor (PMSM) is a synchronous motor in which the rotor uses permanent magnets instead of traditional excitation windings. By replacing traditional excitation windings with permanent magnets, it eliminates the need for slip rings and brushes, resulting in a simple structure yet superior performance.
Permanent Magnet Synchronous Motor Features
Ultra-high efficiency and significant energy savings: Permanent magnets replace excitation coils, eliminating the need for excitation current.
High power factor: Power factor close to 1, low stator current, low reactive power loss, and high grid utilization.
Small size, light weight, and high power density: 30%–50% reduction in size and weight for the same power output, with a power density of 1–2 kW/kg.
Fast dynamic response and high speed control accuracy: Supports vector control and direct torque control, with speed accuracy ±0.1% and millisecond-level dynamic response. Synchronous speed characteristics prevent step loss.
Low maintenance cost and high reliability: Brushless and commutator-free design, low failure rate, and maintenance-free operation. Fully enclosed structure suitable for harsh conditions such as high temperature and humidity.
Low vibration and low noise: Operating noise is typically below 70 dB, suitable for precision equipment and quiet environments.
