Using high-speed sensorless BLDC motor control in medical devices Introduction Brushless DC (BLDC) motors are widely used in medical devices due to their high reliability, high efficiency, low ...

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 Electroni… ...

Having understood the construction and basic operating principle of BLDC motor in the first part of this article, it becomes important to understand the motor control options available for the ...

Set up demo for generating desired PWM output signals using MPC5676 Implement PI algorithm to control speed of the motor Setup 4-wire 2-phase BLDC motor speed control (2000 to 7600 RPM), two motors ...

Demand for low-cost, robust motor drives has spurred increased use of sensorless vector control of induction and BLDC motors — in everything from consumer products to industrial applications, in ...

Power Integrations’ Motor-Expert™ Suite for BridgeSwitch™ IC family includes new control software for three-phase BLDC motor drives. Image provided courtesy of Power Integrations.

The TB9062FNG pre-driver can control BLDC motors using only a simple pulse-width modulation (PWM) input, without the need for any high-performance microcontrollers (MCUs) and software.

To solve the problem without sourcing a new switch, [Jean-Noel] built his own Arduino based Dahlander switch. This consists of three relays that select the wiring configuration for each speed mode.
