Product Description

Permanent Magnet Synchronous Motors or PMSM for short. PMSM is now more and more popular in the industrial applications.

There are several Disadvantages of conventional induction motors.

• Speed control in induction motors is difficult
• At low loads, the power factor drops to very low values
• Efficiency drops at low loads.  This is because, the low power factor causes a higher current to be drawn.  This results in higher copper losses.
• Poor starting torque.  Induction motors have notoriously low starting torque.  Hence, they cannot be used for application such as traction and in lifting loads.  Slip ring induction motors can be made to produce good starting torque by adding resistors to the rotor windings.

With our Permanent Magnet Synchronous Motors, these disadvantages can be overcome case by case in various applications, the motors can be worked at high efficiency and low maintenance cost.

SOME OF Standard IEC /NEMA Frame MOTORS

These PMSM motors are offered to replace some induction motors in the market. The frame is exactly same with the induction motors, but overcome the disadvantages of induction motors with higher efficiency ( approx. 90%).

Advantage of PMSM motors

1. Lower maintenance and longer lifetime- no brush and commutator erosion
2. Lower noise-the elimination of brush contact
3. Higher power to weight ratio
4. Higher efficiency ( in general higher than 90%)
5. Lower temperature rise-more efficient heat dissipation due to winding construction
6. Reduction of EMI
7. Adopt over 5 pairs magnetic poles design, the ability to start and stop fast.

Customized Motors

For customized 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 …….. 450V AC
• Motor speed (RPM): Revolutions per minute of the shaft at full load Voltage
• Application: e.g. traction, air condition, 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.
