Product Description
Our motor cores are manufactured using equipment imported from Japan. Silicon steel is used for excellent magnetic permeability and low iron loss. This results in durable motor cores with high speed and precision control.
During the production process, the stator cores are stamped with high precision using a high-speed stamping machine. The die is constructed from tungsten steel inserts, tungsten steel punches, and precision guide pins. This ensures high production efficiency and stable die production, while preventing problems such as loose film.
Outer ring dimensions range from 20 to 120 mm. After final production, the cores are pressurized and tested on an automatic press.
We insist that quality and honesty come first. Please feel free to contact our team at info@volcanomotors.com for any technical support.

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.

Advantages of Brushed DC motors
- Reduce eddy current
- Lower noise
- Cools the stator core
- Reduces hysteresis loss
- Higher coil filling achievable. We can control 90% for High voltage, while 80% for low voltage
- Various stamping tools available to save initial design
- Large material savings compared to one piece stator
- Various grade of magnet
- Better magnetic properties, low demagnetization rate, and high magnetic consistence
- 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:
- 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.
