What is a permanent magnet synchronous traction machine
The permanent magnet synchronous traction machine is a new type of bearingless motor that applies bearingless technology to permanent magnet synchronous traction machines. With its advantages of energy saving, small size, smooth running at low speed, low noise and maintenance free, it is attracting more and more attention from the lift industry.
How the permanent magnet synchronous traction machine works
1. Principle of operation
In terms of operating principle, the permanent magnet synchronous traction machine is built using a magnetic field as a power support, which in turn results in an efficient conversion between electrical and mechanical energy. Studies have shown that the most efficient energy conversion is achieved through magnetic fields.
2. Principle
At a concrete level, when the stator is energised in three ways, a field force superposition is created with a fixed angle to the permanent magnetic field with multiple sources. The current in the magnetic field is subjected to forces and the interaction between the stator and the rotor produces a steady thrust on it. According to the formula F=nBIL the power output of the motor is related to four factors, namely the number of force points, the permanent magnetic induction, the three stator currents and the rotor action length. At the same time, the turntable structure allows the rotor to have a uniform distribution of force points in relation to the magnetic field, so that the theoretical force values are equal everywhere, which further makes the force uniform at all times. In addition, the power output is controlled by means of an electric current, which corresponds to the different energy outputs during start-up, travel up, travel down and uniform travel, making the power output of the lift of the permanent magnet synchronous traction machine much smoother.
