liftstar electric stacker Electric forklift motor controller has gone through several stages of development

Electric forklift motor controller has gone through several stages of development, and the development of good, then it has gone through several Semi Electric Stackers‍ stages of it?

     1, the battery started directly, just relying on complex adjustments or battery discharge control.

     2, the resistor start

     Loss of the ability to control large, only a limited rate of decomposition.

     3, thyristor controller, also called SCR controller.

     Transistor control makes the possibility of greatly increased.

     4, the bipolar transistor control

     Then compared with the thyristor, the working principle of a more simple, the disadvantage is the high reliability requirements of the circuit.

     5, MOS FET control

     Gate drive current, good parallel control Electric Hand Pallet Jacks‍ features, positive forward voltage is relatively small, relatively low switching losses.
