What is the main role of the motor?

The main role of the motor: turn a kind of energy into kinetic energy and let the machine run.
The motor is a foreign language, an output power device, common motivation, oil motor.
Electric motor, also known as electrical motor, is provided to mechanical use that transforms electrical energy into rotation. Oil motor is provided to mechanical use that can transform the pressure of stress oil into rotating. Easy to install electric motor, but the starting start is poor, the oil motor transmission power is relatively stable, the noise is low, but the device is more complicated.
The type of motor is as follows:
Hydraulic motor: It is used to the output rotation movement. The hydraulic pressure provided by the hydraulic pump can be transformed into a mechanical energy conversion device.
High -speed motor: Gear motor has the advantages of small size, light weight, simple structure, good craftsmanship, non -sensitivity to oil pollution, impact resistance and minimal inertia. The disadvantages are large torque pulse, low efficiency, small starting torque (only 60% -70%of the rated torque), and poor low -speed stability.
Leaves motor; the blades in the rotor groove are in contact with the shell (stator ring), and the hydraulic motor rotating the rotor rotated by the flowing liquid. Compared with other types of motor, the blade motor has the advantages of compact structure, small contour size, low noise, long life and other advantages. Its inertia is smaller than columns, but its anti -pollution is worse than gear motor, and the speed cannot be too high. Work below 200r/min. Due to the large leakage of the blade motor, the load changes or are unstable at low speed.
Low -speed hydraulic motor; radial column plunger motor rod type hydraulic motor is simple structure, reliable work, many varieties and specifications, and low prices. The disadvantage is that the volume and weight are large and the torque pulse is large.
Rador motor: It is a small, low -speed, and high -torque hydraulic motor of the internal meshing of the gear. Its simple structure, good low -speed performance, and strong short -term overload capacity. There is a stator and a activity blade in the motor. The stator, blades and transmission shafts divide the motor into two cavities. Each cavity has a oil port. swing.
Pistons -type pneumatic motor: It is composed of connecting rods, crankshafts, piston, cylinder, body, gas distribution valve, etc. Compressed air through the gas distribution valve, supplying gas to each cylinder in turn, so that the crankshaft is promoted through the link. Its skills mainly come from gas expansion.
