Wannan motor brushless DC micro motor manufacturers use a little common sense

To determine the current value of the size of the current motor load condition whether there are signs of overload, how to measure?

Will power line which a pull up, the meter (please first transferred to ampere file) end connected to the drive power connector is one of the pin and at the other end is connected to the power supply socket of another pin, so can be measured out at present under load that must be spent in the current value, and then accordingly current value to control the motor current / torque control table, so you can learn the current load status is normal or not overload occurs.

For the driver to have protective measures, when the load is too large or improper use will cause large current and the power transistor burned. In order to protect the current exceed the specifications and damage the drive, generally in order to increase the power transistor current or sensor to increase the current protection. Secondly when the motor load is not small, stop turning from motor end echo to drive energy and overvoltage would endanger the driver, which can be with the voltage protection circuit and regenerative energy dissipation circuit to control. Other Hall-sensor normal or not to determine whether it will affect the correctness of the PWM control, which can be judged by the control department and timely warning.
