HSQ series of speed reducer mainly contains following parts:
The interface bracket (part1) is to be cast precisely and mounted on the chassis or car body. The rotor (part2) which are divided into two parts (front and back) are to be cast with light and fine ferrous magnetic materials containing good magnetic conductivity and it is specially made into a form of blade wheel in order to dispel the heat caused by braking. The two rotors are mounted on two sides of the stator in symmetry through the mid joint flange (part 5), keeping with an appropriate gap (adjusted by spacer). The stator (part 3) is a stamping workpiece made of light and high strength material that is magnetic-proof. Around the outside circle of the stator are mounted four sets of magnetic coils with unlike poles, which are wounded on 8 magnetic cores with high magnetic conductivity. The coils (part 4) are to be winded with wires containing characters of high heat resistance and high electric conductivity and be divided into four groups (each group has two) with unlike poles. The mid joint flange (part 5), which is made of fine material by precise machine, is to be connected with the driving shaft of the automobile.
