Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

When motors start across the line, they typically draw five times the running current. This temporary “inrush” is an overload condition. To handle inrush while still providing adequate overcurrent ...

There are several reasons to use a three-phase inverter to run a single-phase induction motor, including isolation from variable power grids, reduction of peak currents and elimination of the starting ...

This application note presents the vector control of a 3-phase AC induction motor using the Z8FMC16100 microcontrollers. This document also briefly describes the series of Z8FMC16100 flash ...

This solid-state thyristor (SCR) switch circuit is perhaps the simplest means of reversing a 3 phase motor. “Static” is a catch-all term that essentially means without moving (mechanical) contacts ...

Many single-phase motors used with refrigeration-duty, semi-hermetic and hermetic compressors require an external relay to assist in starting. How much do you know about these necessary products? An ...

Toshiba has launched two sine-wave pulse width modulated (PWM) drive controllers for three-phase brushless DC motors ...

Toshiba Electronics Europe GmbH has released two sine-wave PWM drive controllers – TC78B043FNG and TC78B043FTG – for three-phase BLDC motors, which can support surface permanent magnet (SPM) and ...
