The purpose of this application note is to illustrate a software-based implementation of sensorless, field oriented control for permanent magnet synchronous motors using Microchip digital signal ...

When used in an appliance, a permanent magnet synchronous motor (PMSM) provides very good efficiency because of its constant rotor magnetic field, which is produced by a permanent magnet on the rotor.

The field-oriented control (FOC) approach offers many advantages compared to other control strategies used with electric motors. Among the most significant benefits is the fact that FOC offers precise ...

STMicroelectronics has released the STM32 ZeST (Zero Speed Full Torque) software algorithm, designed to run on STM32 microcontrollers, that lets sensorless motor drives produce full torque at zero ...

SAN JOSE, Calif.--(BUSINESS WIRE)--Power Integrations (NASDAQ: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today announced MotorXpert™ v3.0, a software ...

motor control based on a six-step commutation sequence; detection of the magnetic angle of the rotor, to perform the commutation at the correct angle (each step corresponds to an angle of 60 degrees); ...

An average electric vehicle (EV) user has no idea about Field-Oriented Control (FOC) algorithm that works silently under the hood. But people in the know of things will swear by its ability to drive ...

Through legislative and social pressures, public attention is focusing more on the energy used to perform basic domestic functions such as food preparation, cleaning, and climate control.

Designers can expect environmental demands to continue to drive the need for advanced motor control techniques that produce energy efficient air conditioners, washing machines and other home ...

Microprocessor control lets variable-speed PMSMs save energy. Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, ...
