　　Cam and groove coupling supplier showed that judgment method is mainly to see the current of motor, motor can not start after through current, may be caused by three reasons;

　　(a) motor step-down start time. Troubleshooting method is to shorten the step-down start time.

　　(b) motor selection is too small to large load, motor driving ability. The solution is to reduce the load or for large motor.

　　(c) if load is too large, you should produce according to the operating rules, can not arbitrarily increase the load.

　　But the motor can not start not though current, it may be caused by the cam and groove coupling:

　　(a) flushing of cam and groove coupling is not enough. The solution method is appropriate to add a working liquid.

　　(b) cam and groove coupling type selection is small. The solution is to increase the coupling specification.

　　(c) characteristics of soft start the overload coefficient is low. The solution is an appropriate choice to start strong coupling.

　　(d) hydraulic cam and groove coupling fault. Emergence of fasteners shear, damage to the impeller failure. The above is a working machine can not start what causes.
