This Application Note describes the design of a sensorless 3-Phase Switched Reluctance (SR) motor drive based on Freescale’s 56F80x / 56F8300 dedicated motor control devices. SR motors are gaining ...
To solve the problem that the rotor estimation accuracy is greatly affected by parameter nonlinearity and high frequency oscillation, when the synchronous reluctance motor adopts the sensorless ...
Aiming at the problem that an Interior Permanent Magnet Synchronous Motor (IPMSM) cannot be smoothly started in zero-low speed range and smoothly transitioned to medium-high speed range by a single ...
[Davide Gironi] shows us how to implement a sensorless brushless DC motor controller (sensorless BLDC) using an ATmega8 microcontroller. In order to control a BLDC motor you need to know its ...
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 ...
Texas Instruments has released a free, interactive online simulation tool that enables motor designers to assess the company’s InstaSPIN-field-oriented-control (FOC) technology. This online simulation ...
Startup techniques employed to overcome the problem of determining magnet position in BLDC designs. Cost-saving and power-efficiency incentives using sensorless motor drivers. Motor-driver solutions ...
Washing controls have used power inverters to control motor speeds for years. Variable-speed control enables a significant simplification of the mechanical system by replacing a clutch and gearbox ...
“Motor controllers with sensorless commutation — this kind of technology proposition didn’t exist anywhere in the world before our intervention,” said Shashikanth Suryanarayanan, founder of SEDEMAC ...
