Expansion: Permanent magnet synchronous motor has obvious advantages such as low power consumption, large torque, low noise, small size, light weight, high speed regulation accuracy, wide speed regulation range and good low-speed performance.
No mechanical deceleration mechanism, no loss of deceleration link, no lubrication and energy saving. The motor directly drives the elevator to run, so the mechanical structure becomes very simple and the safety and equipment reliability are improved. Magnetic steel (permanent magnet) is the core material of permanent magnet synchronous motor. Hitachi HGE adopts patented design: permanent magnet is fixed with adhesive and copper bolt pressing plate to locate magnetic steel. It eliminates the danger that the general permanent magnet synchronous machine directly sticks the magnetic steel to the rotor and damages the motor because the magnetic steel falls off.
