1.The torgue motor is designed differently than other motors. It can obtain stable torgue in low

speed under a restrained condition.Suitable in forced static-torgue situation, or when the

high-speed operation is finished, it needs to retain its restrain mode.

2.Suitable for rolling (lifting) a load. An object with continuous  and constant speed is

rolled (lifted) up under constant tension. When the rolling wheel axle's outer diameter is

enlarged, the rotating torque must also increase, and the speed is slowed.
