Even thought the power was off there was AC at the handle plug and I shorted something. I pulled it apart and found a transistor blown apart. I figured it would be an easy fix. One month, twenty plus dollars in parts and many changes of components it is.... -
In motor control circuits, one must take precautions to keep the motor from feeding back into the power supply, causing the supply voltage to rise, consequently breaking things. But how can this be Unless some external force is accelerating the motor, the.... -
When the motor is connected in this fashion, the netduino activates the transistor, but nothing happens. If i swap the motor with an LED, the LED does light up, so that incidates that the motor isnt getting enough power. So i connect the motor direct to.... -

A servo motor is a special geared DC motor equipped with an electronic circuit for controlling the direction of rotation, as well as the position, of the motor shaft. Because servo motors allows precise angular positioning of their output shaft, they are.... -
The logic power and CAN signals come in from N4 pins 3 through 8. The CAN signals are connected to the MCP2551 CAN physical layer IC, U5. The transmit and receive pins of the microctroller, (U4 pins 5 and 6) are connected to the other side of U5. Lastly, the.... -
The circuit shown above can be used to control a unipolar stepper motor which has FOUR coils (I`ve swiped it off an old fax machine). The above circuit can be for a motor current of up to about 500mA per winding with suitable heat sinks for the SL100. For.... -
A dual DC motor controller that utilizes an H-bridge controller chip. As well as the basic features of the H-bridge driver chip including thermal and over-current protection, the circuit presented in this project supports dual 12V/5V regulated power.... -
The simplest of all motor controllers (besides a beeline on/off switch) is the contactor controller. I advised this contactor ambassador for use in my electric scooter project. It is based about three 12V relays, two 12V batteries, two switches and of.... -
