Continuous rotation, and when keeping motor direction of rotation constant, deceleration mechanism driving load device can be realized operation, stopping,
And changing the function of load device direction of rotation, then the deceleration mechanism can ensure motor in the higher working condition of efficiency
Lower operation, and response speed is improved when the deceleration mechanism changes load device direction of rotation.If two motor can be same
When adjust motor output revolving speed and output power, keep two motor drive deceleration mechanisms speed difference it is constant
Under the premise of, while improving the output revolving speed i.e. raising simultaneously for perhaps reducing by two motor simultaneously or reducing by two electricity simultaneously
Motivation drives the output power of the deceleration mechanism, then includes that the two motor and the application system of the deceleration mechanism can satisfy
The control requirement of constant power load device.

In deceleration mechanism operational process, the revolving speed of planet stent transmission shaft is related to the rotational speed difference of two motor,
Have the advantages that transmission ratio is big, output torque is big, two motor can be in high-speed cruising state always, in two motor
In the state that direction of rotation is constant, the direction of rotation of the planet stent transmission shaft of the deceleration mechanism, driving load can be changed
While device realizes operation, stops and changes the function of load device direction of rotation, deceleration mechanism can ensure motor
It is run under the higher working condition of efficiency, and improves response speed when the deceleration mechanism changes load device direction of rotation
Degree.Two motor of the deceleration mechanism can adjust the output revolving speed and output power of motor simultaneously, kept for two
Under the premise of the speed difference of the motor drive deceleration mechanism is constant, while improving or reducing simultaneously the output of two motor
Revolving speed, the i.e. output power of two motor drive deceleration mechanisms of raising simultaneously or reduction simultaneously, deceleration mechanism energy
Enough meet the control requirement of constant power load device.
