W22 Quattro (marketed in Europe as WQuattro) is a hybrid motor built on the W22 mechanical platform. Its rotor combines an aluminium squirrel cage with high-energy NdFeB permanent magnets: the cage lets the motor start direct-on-line like an induction motor, while the magnets give synchronous speed and high efficiency in continuous operation.
Because speed does not change with load, multiple motors can run in synchronism and be fed from the same inverter, with more precise control. Scalar inverter control needs no encoder or sensor, making the line well suited to variable-torque loads such as pumps and fans. The output-to-frame ratio matches induction motors, so it can directly replace existing units.
Lower bearing temperatures extend service life and reduce maintenance, and the WISE® insulation system is suitable for inverter duty. The motor is supplied in RAL 6021 green. Euronorm supports output and frame selection and energy-saving calculations for W22 Quattro, along with quotations.
Features
Hybrid rotor
An aluminium squirrel cage and NdFeB permanent magnets are combined in one rotor.
Direct-on-line starting
The motor starts from the mains just like an induction motor.
Efficiency beyond IE4
Synchronous operation delivers higher efficiency than a W22 induction motor in the same frame.
Synchronous speed
Speed does not vary with load, making multi-motor synchronisation easy.
Sensorless scalar control
No encoder or special overload relay is needed when used with an inverter.
Full interchangeability
The output-to-frame ratio is the same as for induction motors.
Applications
- Pump and fan systems
- Compressors
- Conveyors and textile machinery
- Multi-motor drives requiring synchronous operation
