DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...

[Robert Murray-Smith] doesn’t like the price of inverters to convert DC to AC. That led him to build a dynamotor, or what is sometimes called a motor-generator set. These devices are just DC motors ...

In the simplest of terms, an AC generator supplies power directly to a 120-volt circuit to run AC accessories throughout a boat, as well as charge the boat’s batteries (through an AC-to-­DC charger).

If you want to convert one voltage to another, what do you do? Well, if you are talking DC voltages today, you’ll probably use a DC to DC converter. Really, these converters generate some sort of AC ...

This document written by Steve Bowling, Application Segments Engineer at Microchip Technology, discusses how motor works and describes the AC induction motor, variable-speed ACIM control, and FOC.

Today it is widely accepted that AC induction motors offer performance improvements, greater efficiency, and reduced maintenance over DC motors. However, when it comes to the access industry the ...
