PMSM Traction Motor

Our Permanent Magnet Synchronous Motor (PMSM) Traction Motor combines high efficiency, high torque density, and a durable, gearless structure. It is widely used in electric vehicles (EVs), elevators, industrial vehicles, and other traction applications requiring strong and stable driving power.

With rare-earth permanent magnet materials and advanced synchronous control technology, our PMSM traction motors provide smoother operation, lower noise, and significantly reduced maintenance compared with induction or brushed motors.

WTP series PMSM motors desgined with higher efficiency of IE5 class. Excellent stator and rotor design. Super strong permanent magnet materials and imported bearings. Advancements design in material science and motor control algorithms. Traction Elevator Motor offering higher efficiency, reliability, and sustainability.

Mainly application for Passenger Elevator (Standard passenger elevators for vertical transportation in buildings) ; Freight Elevator (Goods Lift /Service Elevator), including: Heavy-duty Freight Elevator, Hospital Service Elevator); MRL Elevator System:  Machine-Room-Less

PMSM Traction Motor Features

Flexible Control Options

   • Dual-support traction sheave and brake arm design for superior mechanical performance. Excellent controllability for precise speed regulation and torque output.

High Efficiency

   • Direct-drive system ensures higher transmission efficiency (standard IEC terminology). Efficiency up to 97–98%, reducing energy consumption and operating cost.

Smooth & Quiet Operation

   • Eliminates worm gear mechanism, reducing noise by 5-10dB. Suitable for noise-sensitive applications such as elevators and indoor machinery.

Maintenance-Free Longevity

   • No additional transmission components, truly maintenance-free design

Compact Structure

   • Gearbox-free configuration saves installation space. Gearless design greatly reduces mechanical loss, noise, and maintenance frequency.

High Torque & Torque Density

Strong continuous and peak torque, suitable for traction demands such as EV acceleration and elevator lifting.

FAQ — PMSM Traction Motor

1. What is the difference between PMSM and BLDC traction motors?

PMSM has a sinusoidal back-EMF and supports FOC control, providing smoother torque and higher efficiency. BLDC is usually trapezoidal and may have more torque ripple.

2. Why choose a gearless PMSM design?

It eliminates gearboxes, lowers noise and maintenance, improves reliability, and increases system efficiency.

3. Can torque-speed curves be customized?

Yes, motors can be customized for high-torque low-speed, or high-speed continuous output.

4. What control methods are supported?

FOC vector control, encoder feedback, Hall sensors, CAN bus communication (optional).
