AC Induction Motor Fundamentals
induction motors are available in the market. Different motors are suitable for different applications. Although AC induction motors are easier to design than DC motors, the speed and the torque control in various types of AC induction motors require a greater understanding of the design

Replacing Your DC Motors? Think AC
, either because they are inaccessible or because plant maintenance practices are poor. AC drives generally are smaller and lighter than DC drives for a given torque and speed output, and they are capable of speeds approaching 10,000 rpm. In addition, a single AC drive can control multiple motors

Re: Washer Motor
Most washing machine motors are brushless AC motors and are capacitor start, with a mechanical governor relay that kicks it out of start mode after the motor is at design speed. You cannot use a speed control on these motors, you at best will burn it out, at worse you will catch it on fire. Use a m...

Re: Windmill Synchronization
Typically, grid connected wind turbines are now induction generators; they produce AC, not DC. You said DC, that's why I mentioned inverters. An Induction Generator is basically a standard AC motor that is driven by the wind to above synchronous speed which turns it into a generator inste...

Re: Need recommendation for Power Supply and Speed Control for 12v DC Motor
Interesting, thanks for the advice! I will probably mount the power supply in a separate chassis, since the pottery wheel will get wet by design & I want to keep the AC components completely separate. I've actually considered just running it from a permanent battery, and connecting to a charger wh...

Re: 1 Phase To 3 Phase
hiii all, to be precise, simply, capacitors wont do the job. if one can design an RC phase shift oscillator for power frequencies, it would be fine since these oscillators are used only in the audio frequency range so far as i know. and again, a possible solution may be to give the single phase...

Hitachi's New, More Efficient DC Motor Control System Could Improve EVs
For the most part, electric vehicles use an invertor to change the direct current coming from the battery pack to alternating current to power the electric motor. Direct current [DC] motors are more efficient than alternating current [AC] motors, but aren’t found very much in electric vehicle application because they waste energy starting up and [...]The post Hitachi’s New, More Efficient DC Motor Control System Could Improve EVs appeared first on The Green Optimistic.
