The structure of the hollow cup motor is: back cover, terminal, brush end cover, brush, commutator, cup winding (rotor), rotating shaft, washer, plain bearing, housing, magnet (stator), flange, positioning ring.
The stator consists of a permanent magnet, a shell and a flange. The housing provides a constant magnetic field so that the motor has no iron loss. No soft magnetic teeth. The resulting torque is uniform, allowing smooth operation even at low speeds. At higher speeds, the motor can reduce vibration and reduce noise. Rotor with winding and commutator. The windings are connected to the shaft by a so-called commutator plate. The coil moves in the air gap between the magnet and the housing. The commutation system uses a pair of precious metal brushes to reduce brush sparks. Reduced brush sparks produce less electromagnetic emissions.
Hollow cup motor features:
1, energy-saving characteristics: energy conversion efficiency is very high.
2, control characteristics: start, brake fast, fast response; The speed can be easily adjusted sensitively under the speed operating state within the recommended operating area.
3, drag characteristics: the operation stability is very reliable, the fluctuation of speed is very small, as a micro motor its speed fluctuation can be easily controlled.

Application areas of hollow cup motor:
1, need fast response servo system. Such as the rapid adjustment of the flight direction of the missile, the follow up control of the high rate optical drive, fast automatic focusing, highly sensitive recording and detection equipment, industrial robots, bionic prosthesis, etc., the hollow cup motor can well meet its technical requirements.
2, the driving components require smooth and durable drag products. Such as all kinds of portable instruments, personal equipment, field operation equipment, electric vehicles, etc., the same set of power supply, the power supply time can be extended by more than double.
3, all kinds of aircraft, including aviation, aerospace, model aircraft, etc. The hollow cup motor has the advantages of light weight, small size and low energy consumption, which can reduce the weight of the aircraft to the maximum extent.
4, a variety of civil electrical appliances, industrial products. Using the hollow cup motor as the actuator, the product grade can be improved and the performance is superior.
5, hollow cup motor takes advantage of its high energy conversion efficiency, but also used as a generator; Using its linear operation characteristics, it can also be used as a tachometer generator. Equipped with a reducer, it can also be used as a torque motor.
