hub motor armature speed transfer of thousands, and are excited (or series wound) motor, the rotor and the stator has a coil, there are still large in the low speed torque. Pump motor is an asynchronous induction motor, the stator with coils only, of course, the rotor can also be seen as a coil, but not with copper wire, and not low speed, 1,400 rpm, a 4-pole motor.
hub motor is a generic type (string-excited) motors can be common in the AC and DC power to run.
Series wound AC motor and DC motor structure is no different, such as hair dryer, mill, hub motor, and so used the motor, but did not like the DC motor with permanent magnets to generate magnetic fields. A commutator, carbon brushes, work with electric spark generated noisy. AC induction motors in general no commutator, carbon brush, the input current from the stator windings.
1, hub motor is what kind of motor?
hub motor is a series wound motor, features a brush, working in a spark, noise; torque is larger, does not require phase-shifting capacitor.
2, with the structure of the DC series motors are identical, of course, is not the same coil winding.
3, series motor is the specified sub-coils and the rotor excitation coil is in series. This heavy motor load, the current increase, the excitation current is also large, strong magnetic field generated by the torque will also increase, so a larger starting torque.
4, as mentioned earlier, AC and DC current through the coil impedance varies greatly, 220V DC 220V AC motor with a large coil is not the same, can not be universal.
