Our company, founded in 1995, is a large-scale enterprise specializing in motor manufacturing, with expertise in producing various motors and reducers. The motors produced by our company have a wide range of applications, covering almost all fields. For example, mining, machinery, steel, metallurgy, transportation, and agriculture
A synchronous motor is an AC electric motor where the shaft's rotation speed is perfectly synchronized with the frequency of the power supply. Unlike standard induction motors, it operates at a constant "synchronous speed" with zero slip, making it highly efficient and ideal for high-precision industrial applications.

Synchronous motors can operate over a wide range of power factors, including hysteresis and overrunning.
They can be constructed with a wider air gap than induction motors, which makes these motors more mechanically stable.
Synchronous motors are less costly in certain kW and speed ranges. They typically operate at higher efficiencies at low speeds with uniform power factors.
It can be constructed with a wider air gap than an induction motor, which allows it to be mechanically stroked.
Over-excited synchronous motors can have an over-excited power factor and can be operated in parallel with induction motors and other lagging power factor loads, thus improving the system power factor.
In synchronous motors, the speed remains constant regardless of the load. This characteristic helps industrial drives.
Compared to induction motors, synchronous motors usually operate at higher efficiency.
Components
Stator windings
These are energized with AC power to create a rotating magnetic field.
Rotor
Equipped with permanent magnets or electromagnets, the rotor locks in step with the stator's magnetic field, rotating at synchronous speed.
Encoder (optional)
For precise position feedback in servo applications.
Cooling system
To manage heat dissipation during operation.
Brake (optional)
Usually a holding brake to maintain position when the motor is stopped.
Constant-Speed Machines - Perfect for pumps, compressors, and conveyors because the motor keeps the same speed at all times.
Power Factor Improvement - When over-excited, the motor helps correct poor power factor in electrical systems, saving energy and reducing losses.
Large Blowers and Fans - Works well in ventilation and cooling systems where steady and reliable airflow is needed.
Heavy Industrial Equipment - Suitable for rolling mills, crushers, and mixers that require strong torque and stable operation.
Synchronous Condensers in Power Plants
Helps regulate voltage and maintain system stability by supplying or absorbing reactive power.
Precision Machinery
Supports machines that need accurate and constant speed, such as timers, testers, and measurement equipment.
Modern Technology (PMSM Type)
Found in electric vehicles, robots, and home appliances because permanent magnet versions are efficient and compact.
All of our machines will be fully checked by our quality control department before the shipment. We guarantee all of our machines have a one-year warranty (quick-wear parts not included).
