DC Motor Reversing Circuit Circuit

Motor Control Wiring | By: Diagram mania

Description: A DC motor reversing circuit using non latching push button switches. Relays control forward, stop and reverse action, and the motor cannot be switched from forward to reverse unless the stop switch is pressed first. Circuit diagram Notes: At first glance this may look over-complicated, but this is simply because three non-latching push button […]

Simple DC motor PWN speed control Circuit

Motor Control Wiring | By: Diagram mania

The 555 is ubiquitous and can be used as simple PWM speed control Circuit diagram Circuit Explaination: The 555 Ic is wired as an astable and the frequency is constant and independent of the duty cycle, as the total resistance (R charge + R discharge, notice the diode) is constant and equal to 22Kohm (givin […]

Unipolar Stepper Motor Controller Circuit

Motor Control Wiring | By: Diagram mania

This is a very good integrated circuit. There is no need for any external glue logic to drive the circuit, there is only 2 pins to drive the motor, one for controlling the direction and the other to trigger the stepping pulses. It provides a very compact design that drives 5 or 6 or 8 […]

Stepper Motor Controller Circuit

Motor Control Wiring | By: Diagram mania

I found this circuit in my files. I don’t know where it came from, but it looks like I photocopied it from somewhere years ago. I have been told that it came from "The Robot Builder’s Bonanza", by Gordan McComb. Anyway, I thought that it should be fairly useful, so I decided to post it […]

Pulse Width Modulation DC Motor Control Circuit

Motor Control Wiring | By: Diagram mania

Often, people attempt to control DC motors with a variable resistor or variable resistor connected to a transistor. While the latter approach works well, it generates heat and hence wastes power. This simple pulse width modulation DC motor control eliminates these problems. It controls the motor speed by driving the motor with short pulses. These […]

DC Motor Control Circuit Circuit

Motor Control Wiring | By: Diagram mania

Circuit diagram Notes: Here, S1 and S2 are normally open , push to close, press button switches. The diodes can be red or green and are there only to indicate direction. You may need to alter the TIP31 transistors depending on the motor being used. Remember, running under load draws more current. This circuit was […]

PWM Motor Speed Controller – DC Light Dimmer by IC LM324

Motor Control Wiring | By: Diagram mania

A pulse width modulator (PWM) is a device that may be used as an efficient light dimmer or DC motor speed controller. The circuit described here is for a general purpose device that can control DC devices which draw up to a few amps of current. The circuit may be used in either 12 or […]

PWM 12V DC motor speed regulator

Motor Control Wiring | By: Diagram mania

Reverse engineered circuit diagram of a PWM motor speed regulator out of an oral irrigator water pump. This circuit works quite well, keeping the speed of the small PM motor fairly constant regardless of load. No transistor heatsink is required since this is a switching regulator. The efficiency under high load would be a improved […]

PWM D.C. motor drive Low loss speed control By 4093

Motor Control Wiring | By: Diagram mania

This circuit is a very compact switching regulator for small DC motors. I use it for my small printed circuit board drill (18 Volt, 1.5 Amp), but it is suitable for many other applications (e.g. 12V DC halogen dimmer). Circuit description R1, R2, C1, D1, D2 and schmitt trigger IC1B build a 1kHz oscillator with […]
