Stepper motors are self-positioning, and therefore simple to use. They do not require an encoder to maintain their position nor do they need a servo control loop. Their main drawbacks are vibration ...

How current-control loops in BLDC motors improve performance and efficiency while protecting against overcurrent conditions. The differences between current-control loops, field-oriented control (FOC) ...

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 ...

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 ...

ASI8100 space-saving stepper motor with a built-in drive combines a stepper motor, stepper motor output stage and fieldbus connection in a fully integrated design. These EtherCAT devices mount ...

Rotary motor motion is usually converted to linear through rack and pinion sets, belts and pulleys, and other mechanical linkages. These are effective but limited systems. In contrast, integrated ...
