Product Description

Recommend to take permanent magnet brushless DC motors to replace induction motors for following applications:

1. Variable speed applications
2. High starting torque required
3. Low/high speed applications
4. Minimum motor size required
5. Custom speed requirements, allowing operation at any defined speed (AC motors have limited rated speeds: 2-pole – 3000 rpm, 4-pole – 1500 rpm @ 50 Hz, 2-pole – 3600 rpm, 4-pole – 1800 rpm @ 60 Hz).

Permanent magnet brushless DC motors are becoming increasingly popular in industrial applications.

This 5.5kW 72V electric vehicle permanent magnet motor is designed specifically for electric vehicles operating on 72V DC, which is battery-powered. It can be used in electric forklifts, electric boats, electric tank trucks, and more. The motor dimensions are approximately 165mm, with a flange size of 180x180mm. The shaft and flange configuration can also be customized. The BLDC154 series motors offer output powers ranging from 1.5 kW to 10 kW, with torques ranging from 3 to 20 nm in continuous operation and 7.5 to 50 nm in intermittent operation. They maintain high efficiency over a wide speed range.

Advantages of Brushless DC 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

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.
