Product Description

Any one of the below requirements. We advice to use the PMSM motors

1. Variable speed application

2. Require High Start Torque

3. Low /High speed application

4. Minimize Motor size demands

5. Customized Speed, work at any defined speed, ( the rated speed of AC motor is limited, 2 poles-3000RPM, 4 poles -1500RPM @50HZ, 2 poles-3600RPM, 4 poles -1800RPM @60HZ)

You can refer to the structure of this PMSM motor.


The rotor is made by sintered neodymium Magnet halbach ring, the magnetic force is almost 3 times of bond magnet rotor. The magnetic density is stronger, and it can reduce the coils of stator.  

Hence, you can get the following benefits with this PMSM motor.

1, Minimized Motor size. ( smaller than conventional motors)

2, Start /stop faster

3, Minimize the copper loss

4, Higher efficiency over 90%

5, Can be equipped with the encoder to achieve servo control

6, Economic benefits, High cost-effective

This Small Round shape High efficiency Permanent Magnet Sychronous Motors are designed to apply to servo applications, with low cogging torque, it can be used in the applications which uses brushless DC motors. what’s more, High precision servo application can be realized with the encoder.

Now there are some different diameters are available in the factory, diameter 42mm, 53mm and 62mm, And the length of the motor is adjustable by the output power, motor speed etc.

For examples one of the our motor diameter 53mm, is used in bobbin winder automatic system, this motor is replacing the conventional electric motors. The efficiency of the PMSM motors are increased almost 8%-15%. And because of 10 poles systems, the motor starting is much faster on the line. For more specifications on this leading motors, please contact our technical team by email info@volcanomotor.com

This PMSM motors can be also well used in other textile machinery, packing machine, automatic conveyor belt, medical devices, Industrial automation, Robotics.etc.

Generally, whatever standard motors or customized motors, our professional team can help you work them out.

Advantage of PMSM motors

  • Lower maintenance and longer lifetime- no brush and commutator erosion

  • Lower noise-the elimination of brush contact

  • Higher power to weight ratio

  • Higher efficiency ( in general higher than 90%)

  • Lower temperature rise-more efficient heat dissipation due to winding construction

  • Reduction of EMI

For more information on our PMSM Motors, please contact our technician, Ordinary, we have to know the following information to get a professional proposal:

  • Brushed or Brushless   Customer preference

  • Output power (W)   Horsepower/watts/torque rated at full load speed

  • Voltage (V)   i.e 12v DC …….. 220v AC

  • Motor speed (RPM)   Revolutions per minute of the shaft at full load Voltage 

  • Application   e.g. traction, airconditioning, etc.

  • Duty     Most motors are rated continuous. Some applications however may use motors designed for intermittent duty

  • Configuration/Frame    Our products are according to IEC standard, we also can customize the flange and shaft according to the customer drawing 

  • Controller function     e.g. forward/reverse, variable speed, acceleration profile, etc.
