The design of different three-phase brushless DC motors and how they generate torque. How magnetics, construction, and other factors impact torque, speed, and smoothness in BLDC motors. General ...

Proper evaluation of torque margins across the full motion profile prevents stalling and ensures consistent performance under varying load and speed conditions. Mechanical resonance can cause ...

Vector Control, also known as Field Oriented Control or FOC is an AC motor control scheme that enables fine-grained control over a connected motor, through the precise control of its phases. In a ...

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...

A new motor driver featuring pulse-width modulation (PWM) and serial interfaces ensures quiet and robust motor operation in industrial and consumer applications. The motor driver IC, supporting both ...

This is a modification of the popular AccelStepper library that runs the motors using timer interrupts instead of polling them in the main loop. This allows for more precise step timings and running ...

Motors are changing in fundamental ways, and you can actually hear the difference. Vacuums, air conditioners, and home appliances are getting quieter. They’re also becoming more efficient, able to ...

This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor ...
