    Product Description

    Outer motor model VOLEC45-70 in 3 phase with 27mm length, gross weight round 0.15kgs. In round disc shape. Its rated voltage is 24V and rated current is less than 0.5A, the motor working under continues duty S1. Rated torque is 130mN.m. There are 16 poles of this motor.


    This disc motor come with neodymium magnet in order to reach high torque value, the rotor is coreless, so it's detent-free and the motor is easier to control, also, if a brake is need in the application, we can also added a suitable brake on motor, for the motor frame, IEC and NEMA are available, we also can make customized size frame. 


    Our disc motor's voltage range from 9V up to 48V, from power of 6W up to 120W. They are widely used in household electrical applications, unmanned mechanization field and large propeller industries.

    In the field of household appliances, such a compact and mini motor can provide very strong torque and power output. The body is small and does not occupy space. It is convenient to carry and has low noise. It has the long service life, and is not easy to damage, low price and excellent quality, also.

    Advantages of Outer Rotor Brushless DC Motor:

    • Digital pulse signal control is adopted, digital-to-analog conversion is not needed, and connection with a computer is convenient.The application is the most extensive and can vary within a wide range as required.

    • The rotor position changes little, which is easy to realize optimal operation control.

    • Axial magnetizing magnetic circuit, using new permanent magnetic materials with high magnetic energy product, is conducive to improving the performance of the motor.

    • There is no obvious oscillation in the whole operation area.

    • No accumulation error.

    • Simple structure, low cost, no slip ring and brush, easy maintenance.

    • Can be controlled by open loop, has strong anti-interference capability, and is convenient to start, reverse and position.
