The Power Distributions on Series Connection Motors

The driving mode by two hydraulic motors and reducer is widely used in many types of equipment, which adjusts velocity and torque by the way of changing the relationship of the two motors- series connection or parallel connection. It is generally believed that the power distributions on the two motors are the same, which is to say that the two motors´ load-bearing states are identical. In this paper, using the method of emulation analysis and experiment, the conclusion is drew that there is comparatively large difference about the power distributions on the two motors, and the most part of load is bear by one motor.
