BMT Cycloidal hydraulic motor

The low and stable speed of hydraulic motor is an important technical index of hydraulic motor production enterprises, which directly affects the working performance and life of the machine. The determining factor of the lower stable speed of the hydraulic motor is the nmmin value of the lower stable working speed of the hydraulic system with the hydraulic motor as the power actuator, which is mainly determined by the following factors.

1. The system adopts the qmc characteristics of leakage flow and the tmf characteristics of friction torque loss in the low speed zone of the hydraulic motor.

2. The flow regulating device of the system includes pump control, valve control, flow valve speed regulating valve. The output flow characteristic of a small flow relative to the flow required in the low speed zone of the motor. Workflow characteristics that affect motor governing equations.

3. Drag or control the system. Load characteristics of the object. It affects the quality management and TMF characteristics of the motor as well as the workflow characteristics of the speed regulating device.

4. The control mode of the system, such as the open-loop system, closed-loop servo system, etc., affects the automatic speed regulation characteristics of the low-speed fluctuation zone.
