Discussions about DC Motor PWM Schematic
  • Re: RC car circuit

    When your car turns either way, the two motors have an oposite polarity to one another. Find the transistor outputs from the RF decoder that control the motors and XORthem; use the gate output to control a PWM before the DC BUS (e.g. 1=30%, 0=100%). You'll need basic skills in electronics.

  • Control Board Inside the PIM for GM's Old EV1 Car

    I am looking for detailed schematics for the control brd located inside the PIM of the ev1. The PIM is the box that uses 300Vdc input (from batteries/rectifier) and converts the DC into 3 phase variable frequency AC output, to run the main motor (inductive motor). I converts DC to AC by use of a 3 p...

  • Selection of an AC Motor to Replace the DC Motor

    Hi; In a "Single Facer" unit of our Corrugator machine, the "take up conveyor" has a DC motor 5.9KW 2700RPM. We want to replace this DC motor with an AC motor and inverter. On the driven side, there is a gear box with two sprockets which rotate two rolls on which a belt is installed. As there i
