1 Overview Aluminium cage Flux barrier Permanent magnet Hybrid motor: induction + permanent magnet + reluctance Example picture, not actual geometry
2 Developed lines of product IEC 380V, 60Hz: Frames 80 to 132S 4 poles: 0.75 to 11kW 6 poles : 0.37 to 7.5kW IEC 525V, 50Hz: Frames 80 to 132S 4 poles : 0.55 to 7.5kW 6 poles : 0.37 to 5.5kW IEC 400V, 50Hz: Frames 80 to 132S 4 poles : 0.55 to 7.5kW 6 poles : 0.37 to 5.5kW NEMA 460V, 60Hz: Frames 143 to 213 4 poles : 0.75 to 7.5kW 6 poles : 0.75 to 3.7kW
3 Characteristics Three-phase distributed winding in stator (identical to conventional induction motors). Rotor with aluminum cage and internal high-energy permanent magnets. Starts and accelerates directly connected to the mains, as an induction motor. Operates at synchronous speed (invariant with load). Same frame size of induction motor, for same power. Higher efficiency in the same frame size WQuattro W22
4 Advantages Synchronous operation no I²R losses in the aluminum cage. Higher efficiency compared to Premium Efficiency induction motors high energy savings. Low bearing temperature longer life and less maintenance. No sensors high reliability. Interchangeability with existing installations. No need for special protection relays. Multi-motor operation several motors in synchronism fed by the same inverter.
5 Limitations Limited synchronization capability with inertia not suitable for all applications. Care must be taken in the assembly and disassembly of the motor, due to magnets in the rotor, and special tools may be necessary for the IEC frame 132.
6 SPEED software package (analytical and numerical analysis). WEG is member of the SPEED Consortium – SPEED Lab – Glasgow University. Development tools (software)
7 FLUX2D software (numerical analysis) from CEDRAT – France.
8 PM x LSPM PM (inverter-fed PM motor): - Have no cage in the rotor; - Needs a FOC (field oriented control) inverter and information about the rotor position at any instant (either from an encoder or a sensorless algorithm); - Cannot be directly connected to the mains, even for non- variable speed applications; LSPM (line-start PM motor): - Have a cage in the rotor; - Can be directly connected to the mains; - Do not need an inverter to run in a non-variable speed application; - For variable-speed applications, can be driven by an inverter with scalar control algorithm.
