Benefits of PMSM Motors
 

Constant torque
This type of motor can generate constant torque and maintain full torque at low speeds.

 

Size
The smaller size, lighter weight and less coil provide a higher power density.

 

Cost-effective
With the absence of brushes, there are reduced maintenance costs.

 

Minimal heat
In PMSM the heat is generated on the stator coils and there are no brushes and only minimum heat generated on the rotor, facilitating the cooling of the motor. As they run cooler than induction motors, the motor's reliability and lifespan is increased.

 

Speed range
This type of motor can have a wide speed range with the use of Field Weakening and can adopt the maximum torque/current (MTPA) control strategy during constant torque operation.

Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs): PMSMs are commonly used in electric and hybrid vehicles due to their high efficiency, compact size, and ability to provide high torque at low speeds. They contribute to improving the overall performance and range of electric vehicles while enabling regenerative braking for energy recovery.

 

Industrial Automation: PMSM motors find extensive use in industrial applications, such as robotics, CNC machines, conveyors, and various machinery used in manufacturing processes. Their precise speed control, high torque, and efficiency make them suitable for different automation tasks.

 

HVAC Systems: Permanent Magnet Synchronous Motors are employed in heating, ventilation, and air conditioning (HVAC) systems, including fans and pumps, due to their energy efficiency and ability to operate at variable speeds, matching the load requirements accurately.

 

Renewable Energy Generation: PMSMs are utilized in wind turbines and hydroelectric generators due to their ability to efficiently convert mechanical energy into electrical energy. Their high efficiency is beneficial in renewable energy systems where maximizing energy conversion is essential.

 

Consumer Appliances: Certain household appliances like washing machines, refrigerators, and dishwashers also use PMSMs for their energy efficiency, reduced noise levels, and improved performance.

 

Aerospace: PMSM motors are employed in aerospace systems, including electric propulsion systems in aircraft and satellites, owing to their lightweight design, high power density, and efficiency.

 

High-Precision Motion Control Systems: Applications requiring high-precision control, such as in robotics, CNC machining, and medical equipment, benefit from the use of PMSMs due to their precise speed and position control capabilities.

 

Pump and Fan Systems: PMSM motors are used in various pump and fan applications, like water pumps, vacuum pumps, and industrial fans, due to their ability to operate efficiently at different speeds and loads.

FAQ

 

Q: Can your company make package as customer's requirement?

A: Yes, you only need to provide the packaging design and we will produce it according to your requirements. We also have professional designers who can help you with packaging design.

Q: What kind of shipping methods can you provide?

A: We can provide sea transportation, air transportation and express delivery.

Q: What are your prices?

A: Our prices are subject to change depending on supply and other market factors. We will send you an updated price list after your company contact us for further information.

Q: How about the shipping fees?

A: The shipping cost depends on the way you choose to get the goods. Express is normally the most quickest but also most expensive way. By seafreight is the best solution for big amounts. Exactly freight rates we can only give you if we know the details of amount, weight and way. Please contact us for further information.

Q: Do you guarantee safe and secure delivery of products?

A: Yes, we always use high quality export packaging. We also use specialized hazard packing for dangerous goods and validated cold storage shippers for temperature sensitive items. Specialist packaging and non-standard packing requirements may incur an additional charge.

Q: What is the maximum speed of PMSM motor?

A: The maximum speed of the motor controller is 7500 rpm and the rated speed of PMSM is 6500 rpm. When the motor speed exceeds the base speed (rated speed), the motor needs the field weakening current provided by the controller.

Q: How can I control my PMSM speed?

A: Speed regulation of the PMSM is performed through the designing of Proportional Integral (PI), Proportional integral derivative (PID), Sliding mode controller and Sliding mode controller plus PID controller as a speed regulator which is the part of the PMSM drive.

Q: Is PMSM motor run on AC or DC?

A: The Permanent Magnet Synchronous Motor (PMSM) is an AC synchronous motor whose field excitation is provided by permanent magnets, and has a sinusoidal back EMF waveform. The PMSM is a cross between an induction motor and brushless DC motor.

Q: What are the different types of PMSM motors?

A: PMSM types depend on how the magnets are attached to the rotor, as well as the design of the rotor. Permanent magnet synchronous motor can be classified into two types: Surface permanent magnet synchronous motor (SPMSM) Interior permanent magnet synchronous motor (IPMSM).
