Cd Rom Motor Controller Circuit


You may need more external power to drive the motor or maybe you have used a wrong pinout on motor.

Attach a closeup photo of your motor.

i think i am using as Connect with us All About Circuits Home Forums > Electronics > General Electronics Chat > How to drive a cd rom spindle bldc motor without using a driver IC . similar with other drivers (BD7959EFV, MC33033 , KA3080, etc)

There is also a nice write up of a custom igbt inverter driver here:

The AZ5954 is available in HSOP-28 package. Cd Rom Motor Hack I think it is a proper low voltage motor for our project. Collection Intro Intro: Run a CDROM Brushless Motor With ArduinoA brushless dc motor or BLDC is a type of motor without any brush.

Using the coil inputs A1 A2 A3 i've managed to move the motor a little more than 180 degrees ..

These 36 steps are divided into 6 parts of a unique sequence. Travis Fagerness Microsemi's New Inductive Sensor Interface ICs The new Ics are based on inductive sensing technology, eliminating current Hall-effect sensors currently used.

I am only getting 500rpm, it would be great to get 3,000 or so. Published on Oct 16, 2014In this video i show how to control BLDC motor that you have salvaged form an old CD/DVD drive very easily. We'll also learn how to analyze circuits that contain more than one ideal diode in conjunction with resistors and DC power sources. Supply voltage is +5V & 800mAh.

waiting for your response...!!!

really helpful thanks alot

hmm....ohk so it was easy, But can we control a high power (24 volts 4.4 am) bldc 3 phase

if so how??

Can you tell me approximate power of these cd rom bldc motors?
