At what applications you need Brushless DC motors replace conventional wound AC motors.
Any one of the below requirements.
1. Variable speed application
2. Require High Start Torque
3. Low /High speed application
4. Minimize Motor size demands
5. Customized Speed, work at any defined speed, ( the rated speed of AC motor is limited, 2 poles-3000RPM, 4 poles -1500RPM @50HZ, 2 poles-3600RPM, 4 poles -1800RPM @60HZ)
Product Description
Intelligent pump systems that improve the way you use water and provide added value, accommodate a wide range of flow demand, allowing to use the water they need, when they need it.
Currently, the VFD(Variable speed driver) + AC motor pumps system is used to achieve the constant pressure. But efficiency is not high, there is a lot of energy waste of this systems. Because the efficiency of AC motor reduce sharply while excess the rated speed. Compared to AC motors, brushless DC motors have higher efficiency for a wide speeds. Therefore, the brushless DC motor+ controller is tending to replace the VFD+AC motor pump system.
Various Constant Pressure Pump Systems
VFD + AC Motor | Controller + PM Motor | ||
Advantages | Intelligent pump systems that improve theway you use water and provide added value,accommodate a wide range of flowdemand, allowing to use the water they need, when they need it. | ||
VFD/Controller Efficiency | 95%-98% The signal is not sinesoid,weaken the motor efficiency | >98% | |
Motor Efficiency | Rated Speed | 70%-85% | >88% |
Variable speed | reduce sharply | Maintain at high level, over 80% | |
Example P=750W | 75-85% @ Rated Speed lower than 70% @500RPM | over 88% @ Rated Speed Maintain at 80% @500RPM | |
Start Torque | Low | High | |
High Speed Ability | 2 poles-3000 RPM 4 poles-1500RPM @50HZ | 10,000+ RPM | |
Cost | - | a little higher | |
Install | IEC/NEMA/Customized ,substitute for each, noneed to rebuild the pump structure | ||
*The PM motor is able to control at lowspeed with high efficiency. The PM motor system has high efficiency |
1.1KW 2900RPM Centrifugal Pump motor is one of our brushless DC motor motors used in centrifugal pumps. Which replace the same power AC motors. The efficiency is much higher though the initial cost is a little higher. But for long terms, the energy saving of Brushless DC motors and free maintenance, the benefits you get will obviously considerable.
Configuration
*CAN MAKE ACCORDING TO YOUR REQUIRMENT
Advantage of Brushless DC motors
Lower maintenance 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
For customized DC 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, airconditioning, 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.
