What is the vibration of electric motors?
May be the following situations1, if the idle speed is significantly faster, but not a sound or sound load personnel belongs to a phase dislocation, and the motor line (phase line) and Holzer (small line) take the wrong line;2, the motor can not start their own need to jump but have all the normal time jitter will ring manned, which belongs to the motor Que phase and three phase motor (thick line) with no electricity;
3, the motor is not loaded, all normal, the speed will not be obvious fast, but manned will ring or shake, belong to Holzer contact is not good, not all is just one of the line;4, the motor start normal, manned can also, but that is, the controller is started, speeding, and Holzer signal in advance commutation, this simply adjust the controller on it;
5, start abnormal, a start on the trembling, motor speed is slow, that is, Holzer bad, or bad contact, so that less one Holzer work.Electric cars are divided into alternating current electric vehicles and direct current electric vehicles. Generally speaking, electric vehicles use batteries as their energy source, and through the controller, motor and other components, the electric energy is converted into mechanical energy movement, so as to control the current size and change the speed of the vehicle. The first electric car was made in 1834. It was driven by a DC motor. Today, electric cars have undergone tremendous changes, and there are many kinds of electric cars.
