(l) The permanent magnet governor drives the motor to start no-load before starting the load. After the motor reaches the rated speed, the air gap of each permanent magnet governor is gradually reduced through the control system to tensify the conveyor belt slowly and steadily, and the conveyor belt accelerates to full speed smoothly; The belt conveyor can be controlled to gradually overcome the inertia of the whole system and start steadily under heavy load condition; The start of the conveyor belt is very smooth, the speed gradually rises slowly from zero, the acceleration is continuous, and the soft start without impact is realized.
(2) The permanent magnet governor not only reduces the starting current of the motor, reduces the thermal shock load of the motor and its impact on the power grid, thus saving electric energy and prolonging the working life of the motor, but also effectively reduces the destructive tension of the transmission system on the conveyor belt and eliminates the oscillation generated during the starting of the conveyor. It can also greatly reduce the starting impact of the transmission system itself, prolong the service life of key components such as belt and roller, ensure the safe and reliable operation of the equipment, and effectively reduce the cost of equipment maintenance and failure time.
(3) When using a permanent magnet governor, because the motor is selected based on motion conditions rather than starting conditions, the power and size of the motor can be minimized, and unnecessary equipment investment and operation cost can be reduced.
(4) The permanent magnet governor system can prevent the power and torque input to the belt conveyor from exceeding the safety limit, so as to ensure that the belt conveyor cannot run when overloaded, so as to protect other parts of the system;
(5) The starting factor of the permanent magnet governor is about 1, and the strength of the selected belt can be reduced by about 30%.
