Permanent Magnet Electric Motor wind turbine motor With Low Current And Constant Torque 200kw
Permanent magnet motors feature rotors with permanent magnets.
This technology provides the motor with significant advantages such as higher efficiency and a greater power density per frame.
They are driven by frequency inverters, which offer constant torque across a wide speed range, operating even at low speeds with efficiency levels above induction motors without requiring forced ventilation.
W21 Magnet motors are low speeds, low noise levels and energy saving.
When replacing an IE2 (GB3) induction motor with a TYP Magnet Ultra Premium, the energy cost saved in one year would be approximately 9000 RMB*.
*Comparison between 37kW 1500 rpm motors, considering 24hours 365 days in operation and average energy cost as 1 RMB/kWh.
Attributes and advantages of the TYP Magnet motor
✓ Superior efficiency regardless of speed or load
TYP Magnet motors present superior efficiency regardless of speed or load, saving up to 30% in comparison to induction motors driven by frequency inverters.
✓ Bearing life up to 100,000 hours
The TYP Magnet motors are equipped with bearings offering an L10 life of up to 100,000 hours. All motors feature open bearings and endshields with grease nipples which permit re-lubrication and consequently a reduction in stoppages for maintenance.

*Considering continuous operation, ie. 24 hours 365 days operation.
Permanent Magnets
The TYP Magnet utilises powerful permanent magnets made from a combination of neodymium, iron and boron (NdFeB), and commonly referred to as rare-earths magnets. These magnets are around eighteen times stronger than traditional Ferite Magnets.
In order to provide superior mechanical strength and corrosion resistance, the Neodymium/Iron/Boron magnets are covered with a protective epoxy coating.
Thermal Protection
TYP Magnet motors have PTC (Positive Temperature Coefficient) thermistors embedded in their windings which offer full protection against overheating produced by phase loss, overload and under or overvoltage.
Constant torque in a wide speed range
TYP Magnet motors can operate over a wide speed range at constant torque, without the use of forced ventilation. This characteristic makes them ideal for applications requiring speed variation and constant torque, even at low speeds, without the need for an encoder.
TYP Magnet motors are able to operate at up to 30% above their rated speed without the necessity to utilise special components.
TYP series high-efficiency permanent magnet frequency conversion synchronous motors are widely used in injection molding machines, air compressors, pipe making equipment, hydraulic machinery, food machinery, cement pipe making machines, plastic extruders, wire drawing machines and pharmaceutical equipment.
TYP series high-efficiency permanent magnet inverter synchronous motors must be used in conjunction with permanent magnet motor inverters. The rotor of this series of motors is built-in permanent magnet structure, and the special design of different alternating and straight axial magnetic circuits makes this series of motors have a certain convex pole torque.
The rotational speed of TYP series high-efficiency permanent magnet frequency conversion synchronous motor is synchronized with the rotating magnetic field of the stator, there is no rotational difference, which saves the rotational power, and makes TYP series high-efficiency permanent magnet frequency conversion synchronous motor have high efficiency in the whole speed range, and the energy-saving effect is obvious.
