Permanent Magnet Electric Motor With Low Current And Constant Torque Wide Speed Range for Pharmaceutical Equipment
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.
Energy Savings
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.
Key Features
Superior efficiency
Regardless of speed or load, saving up to 30% vs induction motors.
Bearing life
Up to 100,000 hours L10 life.
Permanent Magnets
NdFeB rare-earth magnets, 18x stronger than Ferite.
Thermal Protection
PTC thermistors for overheating protection.
Attributes and advantages of the TYP Magnet motor
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.
Induction motor
20,000 h
TYP Magnet motor
100,000 h
*More than 10 years of continuous 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.
Wide Application Range
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.
Motor Requirements
TYP series motors must be used with permanent magnet motor inverters for optimal performance.
Synchronized Operation
Rotational speed is synchronized with stator magnetic field, eliminating rotational difference.
Energy Efficiency
High efficiency across entire speed range with obvious energy-saving effects.
