Product Description
Like all other motors, BLDC motors also have a rotor and a stator. The BLDC motor stator is made out of high performance silicon steel sheet stacked up to carry the windings and the rotor is made out of permanent magnets. Our winding is 100% copper and H class.
BLDC motors are a derivative of the most commonly used DC motor, compare with the brushed DC motor, BLDC motors have better performance curve characteristics. The major difference between the two is the use of brushes. BLDC motors do not have brushes (hence the name “brushless DC”) and must be electronically commutated. This change make the brushless dc motor can provide more efficiency than brushed DC motor and less maintenance cost.
2.5KW 72V 1500rpm/3000rpm Hall Sensor Brushless DC Motor is one of our popular project. It is widely used for elective vehicle such as e-bike, electric tricycle, golf cart, electric sightseeing, small cars and so on.

Advantages of Brushless DC motors
- Lower Maintainance 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
- Simple structure
- 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 …….. 220V 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.
