You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors require carefully timed signals used in a process called Electronic ...

Brushless DC (BLDC) motors are standard fare in low-precision, speedy RC applications. The control schemes needed to run them slowly or precisely go deep into motor theory and might put these motor… ...

Maxon Precision Motor's newly released DC servo motor controller, the ESCON 50/5 OEM module. This mini OEM plug in module is a 4 quadrant Pulse Width Modulated (PWM) servo motor controller that ...

The HC4040 provides a 7.2-MHz clock to CT0 and triggers CT0 at 28 kHz (7.2 MHz/256). The result is a variable-duty-factor PWM waveform at CT0's output (O 0).Q 1 and Q 2 buffer and boost the waveform ...

The BiSS interface, which complies with the TIA/EIA RS-422 standard, has two additional wires that supply dc to the encoder. It’s hardware-compatible with the SSI interface described below.

This, in turn, determines the speed of a dc motor. For accurate speed control, a tachometer connected to the motor shaft sends a voltage signal back to the controller (drive).
