The ability to control the motors’ speed and rotation is the design key of drones, making the electronic speed control (ESC) module an added value and a fundamental part of a drone. In this article, ...

DC motors are used extensively in industrial variable speed applications because of most demanding speed-torque characteristics and are simple in controlling aspects. This paper presents a DC motor ...

Many of us will have experimented with brushless motors, and some of us will have built our own controllers rather than using an off-the-shelf part. Doing so is a good way to understand their ...

This is yet another project born of necessity. It’s a simple circuit, but does exactly what it’s designed to do – dim LED lights or control the speed of 12V DC motors. The circuit uses PWM to regulate ...

The folks over at the [Barkhausen Institut] are doing research into controlling autonomous fleets of RC cars and had been using off the shelf electronic speed controllers (ESCs) to control the car ...

A recent development in UL standards can save you space, time, and money. Like most things, manual motor controllers and disconnect switches have their advantages and disadvantages. Unlike disconnect ...

Before continuing with the explanation started in Part 2 of the switched-modeoperation, the timer and timing system for the ST7MC motor control cellneeds explanation. All motor timing is driven by one ...

Using pulse outputs from a PLC is a cost-effective way to get simple motion. Most, if not all, PLC manufacturers provide a way to control servos and steppers using a pulse train signal. So when a ...

We know that the rated rotational speed of an industrial motor is based on two fixed factors: the number of poles and the supply frequency. So if you install a 4-pole, 480V motor in a 480V, 60Hz ...

There’s a growing community of do-it-yourself ebike builders that are turning old bicycles into super powerful electric bikes. Using a motor, batteries, a speed controller, and their engineering ...
