Motor design Definition and 15 Threads

A mechanical differential is heavy and inefficient. To try and design an efficient e-rickshaw I would like to use a hub motor for each rear wheel. My initial enquiries suggest that wiring the motors in series would theoretically emulate a differential by maintaining the same same current and...

Hello everyone, I wanted to build an electric motor, and I have done quite a bit of research on it. However, all the links that I get are for “simple motors”, which are essentially just a D battery, a kitchen magnet, and coil of copper wire. I have tried these already, but I wanted to build a...

I am a beginner in Electronics and motors, and I want to build a DIY device that is like this I am just wondering how powerful is that motor that turns the globe in the device, which would hold the cat waste and litter. I am looking to get a powerful enough motor from Amazon.ca but just not...

Here are the details. I started with a nut and bolt, and drilled a hole down the center of it. I inverted and glued into place a carbon fiber rod in the hole. I glued a bit on the end of the bolt. I wrapped magnet wire around the bolt on each side of the rod 400 times. I made a commutator using...

Shorting rings (also called Faraday rings) are commonly used in loudspeakers to reduce the back emf that is induced in their voice coils. Could something similar, i.e. shorted turns of wire that are placed in the same plane as each of the windings in a DC motor, be used to reduce the back emf...

Hello, I am after some help to try and understand SVM implementation is a micro that controls a motor. As I understand it one of the advantages of using space vector modulation over sinusoidal PWM modulation in motor control is that it can control the phase voltages such that the line-to-line...

Summary: For the same mass of copper wire, would more turns or greater thickness create a stronger magnetic field from a coil? So I am attempting to make a brush less DC motor, and I am wondering whether the coils would create a greater magnetic force if there are more turns or if the wire is...

I'm a starter in permanent magnet motor design, and learn to use the Ansoft Maxwell just yesterday! Hope you guys could give me hand, if there have some proplems in my process of designing and software using, Thank you！

Hello, is there anyone who knows how WEG managed to get IE4 efficiency rating for their motors while keeping Aluminum for cage on rotor? http://ecatalog.weg.net/tec_cat/tech_motor_sel_web.asp# Best regards

1. The two rotors (purple, green) are electricaly isolated but mechanically fit to rotate along same axis 2. The motor action on the left side rotor will move the armature set, this will produce currents in right side rotor that will pass via a variable load. 3. do you see the magnetic fields...

is there anyone who knows a company that can design single phase induction motor prototypes in the UK..Thanks for your help

I want to design a single phase induction motor (1/3 HP,50Hz,220V). I face a problem to design the main dimension of stator and Slot shape and Rotor skew angle . Would you give some idea for design ? or any related book and software ?

I've been looking at the undergrad catalog of my school and I haven't noticed any classes that teach motor design. I found classes on drives and motor control but nothing on the actual design of motors/generators. I always thought electric machines was a fundamental topic that all EE curriculums...

Homework Statement Hi, well my task is to construct a DC motor. With 25w rotational mechanical output power. It cannot draw more then 5A current, and has to have 3 or more poles in rotation. The motor must be brushed/commutated. There is a max of 30v D.C. input. The motor needs to be built and...

hello everyone my graduate project is 10-hp 3-phase induction motor can anyone teel me where to buy parts (stators,rotors,frames...etc) from USA or any other i need the company (or shop) site so i choose the required one for my design specification something like digikey for electronic...
