:Stepper Motor ChopperStepper Motor VoltageStepper Motor Output · The 12-V is switched through either Q5 or Q6 in response to a pulse from a timing circuit (not shown). The 5-V is applied through D1 and D2. These diodes keep the 12-V pulses from backing up into the 5-V power supply. The bilevel drive is more complex but allows the stepper motor to have more torque at higher stepping rates.

Bipolar chopper drive circuit. In today’s blog we’re going to examine a bipolar chopper drive, a common method for precision current control in stepper motors. The simplest way to take a look at its operation is by using a basic schematic of it. Let’s use our one ohm, one millihenry, and one amp motor again and wire it into the circuit as
