MATERIAL & DESIGN
Permanent magnet synchronous motors are built by using permanent neodymium Iron Boron (NdFeB) magnets embedded in the steel rotor to create a constant magnetic field and won’t loss of field at 1800
C, its winding made with Class F insulation and processed with double varnish impregnation, ensure that the coils can withstand abnormal voltage fluctuations and the impact of multiple types of harmonics.
The stator inside the motor carries windings connected to an
AC supply to produce a rotating magnetic field. Then at synchronous speed, the rotor poles lock to the rotating magnetic field.
The inherent efficiency of a permanent magnet motor is higher than an induction motor. Both motors use a three-phase design through fully optimized performance. The eddy current losses in permanent magnet motors will be far lesser than in induction motors. Moreover, the slippage as in like induction motors is eliminated in permanent magnet motors thereby improving the heat efficiency.
It has the feature of high energy saving by tracing the loading power and changes speed while the system is running at partial load and
maintains the efficiency level as high as when it is running at full load. While comparing with other frequency conversion induction motor,
permanent magnet motor has a wider range of speed control, more excellent in performance, and keep efficiency level high while running at
lower speed, much better performance efficiency than IE4.
The permanent magnet synchronous motor designed to work from -150C to +450C ambient.
Advantages of RMX Series
Low torque ripple
This motor has a low torque ripple and hence can generate constant torque.It can maintain full torque at low speeds.
High efficiency
These motors full-load efficiency is higher than an AC induction motor.It's a rotor magnet made by using a permanent magnet,so this motor has high effieciency.
High power density
The smaller size and less coil make a high-power density.So,it makes high speed at a low noise level.The heat transfer is also better,and the cooling system is simple.
Low maintenance cost
These motors have not any brushes,so it has a low maintenance cost.But it needs to high initial cost.
Low heat generation
It has only stator winding and no brushes,so its heat generation is low compared with brush motor.Because its rotor hasn't any coil,so heat generation is less.
Compact & Small Size
It may offer a smaller size for more compact mechanical packages.
DC Power Source
Don't need an extra DC power source for it. The AC supply is provided on the stator and the permanent magnets are on the rotor.
Efficieny of Fixed Speed Compressor vs RMA Series
Life cycle cost of IM fixed speed compressor
The largest cost of compressor during its lifetime is the power required to operate the compressor and energy cost amounts to the 80% of the life cycle cost.
PMSM with INVERTER DRIVE COMPRESSOR
Screw Compressors operating with high efficient permanent magnet motor with inverter drive, brings an opportunity of potential energy savings of 27%
Energy Consumption of fixed speed compressor
The conventional fixed speed compressors work with the principle of full-load and no-load control operating between two pressure set points. The compressor goes off load
when the pressure reaches maximum set pressure and power consumed during the idle running can be excessive and large amount of energy wasted
Energy Consumption of induction motor VSD compressor
The induction motor with variable speed drive compressors understands the plant requirement and adjust the flow in accordance
with the air demand. These compressors ensure there is no energy wastage when the
plant air demand is low thereby reducing the compressor life cycle cost.
Energy Consumption of PMSM Inverter compressor
The permanent magnet motor with inverter drive understands the plant air requirement and adjust the flow in accordance with the air demand.These compressors ensure there is no
energy wastage when the plant air demand is low and further it is much more efficient than the induction motor variable speed drive compressors as there is no slippage losses within the permanent magnet motor and assures for higher efficiency.
