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
- 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.
