This application note presents Z16FMC microcontroller used to control 3-phase brushless BLDC motors in a sinusoidal PWM modulation mode. It discusses the ways in which to implement sinusoidal PWM ...
San Diego, Calif.—ROHM Electronics has introduced an H-bridge driver IC line, offering designers a simple upgrade path to pulse-width modulation (PWM) speed control using either analog or digital ...
In my previous article, I described the four most common methods for motor and pump control: input voltage, input voltage pulse-width modulation (PWM), external PWM, and 0–5V DC analog speed input.
This article describes ongoing internal project activities at eInfochips in the control systems domain for applications in motor and engine controls aimed for aerospace and automotive segments.
The motor-speed-control circuit in the figure shows an SG3524 pulse-width-modulation (PWM) IC, U2, driving the high side of a motor through a p-channel FET, Q1. The motor terminal voltage is more ...
Toshiba Electronics Europe has introduced two new sine‑wave pulse‑width‑modulated (PWM) drive controllers designed for three‑phase brushless DC (BLDC) motors, expanding its motor control portfolio.
Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...
Choosing the right motor and VFD type depends on a variety of factors; however, it is necessary to analyze how the motor changes when the speed is reduced. The experts at eMotors Direct outline ...
