Product Description

These motors with our controllers together, which build the the intelligent pump system, the system is composed of a control panel, motor with sensor, pressure sensor, and a water pump. The current case is 220V AC/380VAC power supplying the controller to control the motor, meanwhile the motor sensor transfers the location signal to the controller. The pressure sensor in the pump system transmit the pressure value to the controller, based on these pressure value, the controller carries on the real-time speed control. thereby achieve the function of constant pressure of the whole pump system.


Moreover, the controllers can be connected to the buses, the controller can control different motors, if the pressure is insufficient, the other motors would work simultaneously to keep the constant pressure. meanwhile, to avoid other pumps from rust.

 Compared to asynchronous motors, the permanent magnet DC motors have a lot of advantages

1. High efficiency. At constant speed that both asynchronous motor and permanent magnet DC motors can work at high efficiency. But using asynchronous motor, when the motor speed is changed, the motor efficiency goes down sharply, but using the permanent magnet DC, at a wide speed range, the motor efficiency keep at a high efficiency. 


2. High efficiency of controller (driver) conventional constant pressure pump system is VFD(variable frequency driver)+ electric motor, the efficiency of the VFD is only 80% to 90%, but with our controller + permanent magnet DC motor, the efficiency of the controller is up to 98%. 


3. When the conventional electric motor pump switches on, it keeps working at its constant speed, most of the time, the pump doesn't need the full load operation, this wastes a lot of power long terms. Pumps with our permanent magnet motor, works at an optimum speed (rpm) to meet the real time water needs and provides great deal of energy savings as well as producing targeted constant output water pressure.

Motors in intelligent pump systems


Advantages of Brushless DC motor:

  • 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



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.
