The difference between brushless and brush is generally used for DC motors. AC motors are not classified by brush or brush.
The brushless AC motor produced by our company is the largest in china. There is not much difference in composition, requirements for maintenance and low maintenance, cooling the stator winding more convenient, small inertia, easy to improve the system of fast corrugated pipe coupling, suitable for high speed and high torque working condition, smaller size and weight under the same power.
1, direct current motor with DC, AC motor with alternating current;2, the DC motor needs a reversing device, which is divided into brush and brush. The brush DC motor is changed by commutator, and the brushless motor is reversed by circuit logic;3, AC motor is divided into three-phase AC motor (divided into: synchronous and asynchronous), single-phase AC motor.4, the difference between AC asynchronous motors and synchronous motors is that the rotor of induction motors is non-magnetic (usually copper and aluminum), and the rotor of synchronous machines is permanent (or rather Yu Yongci).5, the difference between single-phase AC motor and DC motor: single-phase DC motor stator or rotor is a permanent magnet (or the equivalent of a permanent magnet, namely: the fixed polarity does not change), and the rotor single-phase AC motor is non magnet, also does not need to be electrified (usually cage). If the single-phase AC electric current is applied to the brushless DC motor, the motor can be operated without the power supply reversing logic circuit.
