Product Description

As far as we know that the motor 100% needs the stator and rotor, we have a team and the chief engineer is from Australia, who has been in designing

the motors over 32 years. We have the full experience that we could help you finish the design of the motor and stator. For this type VOL-WSRS250, the

outer diameter is very big, it could fit your big power motor requirement. And also, the magnets inside are always neodymium types, such as N42SH, N38UH and so on.

Regarding the coil winding, we use the automatic machine to do, it will save the cost and bring your much more benefit. The poles of this components are

always 24 poles or 36 poles, but OEM is always fine. While you want to build up a new electric motors, generators and transformers, we really want to give

you some suggestions, about the multi strands, speed, and big power 60KW, it will fit most of the motor design.

We insist that quality and honesty come first.

Motor construction

Brushless dc motor also have the stator and rotor same like the common dc motor, but it cancel the brushes. The stator used by silicon steel sheet and the rotor make

by permanent magnet. It can be 2 poles to 8 poles just as you wish. Different with the brushes dc motor, the commutation of the BLDC motor is electronically controlled.

We will use the hall sensors to do it. Also can use the magnetic encoder.

*WE CAN MAKE ACCORDING TO YOUR REQUIRMENT

Winding stator and rotor list

l Reduce eddy current 

l Lower noise 

l Cools the stator core 

l Reduces hysteresis loss 

l Higher coil filling achievable. We can control 90% for High voltage, while 80% for low voltage 

l Various stamping tools available to save initial design

l Large material savings compared to one piece stator

l Various grade of magnet

l Better magnetic properties, low demagnetization rate, and high magnetic consistence.

l Multi-poles ring magnet: more stable & stronger magnetic flux to lower motor space and improve performance and lower spacer.

 Designed experiences for winding stator and rotor,

For customized DC Motors, please contact our technician. Ordinary, we have to know the following information to get a professional proposal:

Ø Brushed or Brushless Customer preference

Ø Output power (W) Horsepower/watts/torque rated at full load speed

Ø Voltage (V) i.e 12v DC …….. 220v AC

Ø Motor speed (RPM ) Revolutions per minute of the shaft at full load Voltage

Ø Application e.g. traction, air condition, etc.

Ø Duty  Most motors are rated continuous. Some applications however may use motors designed for intermittent duty

Ø Configuration/Frame Our products are according to IEC standard, we also can customize the flange and shaft according to the customer drawing

Ø Controller function e.g. forward/reverse, variable speed,

acceleration profile, etc.

Q:Motor has been running then fails to start,what to do?
A:Likely cause: Fuse or circuit breaker is tripped. 

      What to do: Replace the fuse or reset the breaker.

     Likely cause: Armature is shorted. Motor may make a humming noise and the circuit breaker or fuse will trip.
     What to do: Disassemble motor and inspect the armature for a burnt coil. Inspect the commutator for burnt bars. If this condition exists, the motor needs to be replaced.

     Likely cause: The brushes may be worn down too far and no longer make contact with the commutator.
     What to do: Check the brushes to make sure that they are still making contact with the commutator. Contact manufacturer for brushes.

      Likely cause: Controller may be defective.
      What to do: Verify voltage is coming out of the controller.

Q: On initial installation, motor fails to start up,what to do?
A: Likely cause: Motor is incorrectly wired
     What to do: Verify that the motor is wired correctly.

     Likely cause: No output power from controller.
     What to do: Measure voltage coming from the controller.

     Likely cause: Motor is damaged and the armature is rubbing against the magnets.
     What to do: Disassemble motor and see if the armature can be realigned by reassembly. Motor may have to be replaced.

Q:  Motor takes too long to accelerate,what to do?
A:  Likely cause: Motor controller not properly set.
     What to do: Adjust the acceleration trim pot of the controller.

     Likely cause: Brushes are worn.
     What to do: Verify brush length.

     Likely cause: Bearings may be defective.
     What to do: Inspect bearings. Noisy or rough bearings should be replaced.

Q:  Motor runs in the wrong direction,what to do?
A:  Likely cause: Incorrect wiring
     What to do: Interchange the two motor leads.

Q:  Motor runs OK but has a clicking noise,what to do?
A:  Likely cause: Suspect a burr on the commutator.
     What to do: Remove burr from commutator using a commutator stone.
