How to design a motor with a given set of requirements?

AI Thread Summary
To design a motor that meets specific requirements, including being a 3-phase synchronous motor with a 480V, 50Hz output and a hysteresis type using alnico, initial design values are crucial. The motor must deliver a torque of 0.6 N.m, with dimensions not exceeding 150 mm and an air gap of at least 0.5 mm. A rotating magnetic field will be generated in the air gap, and the rotor will function similarly to an induction motor with a solid steel rotor. References such as Tuomo Aho's thesis on electromagnetic design can provide valuable insights and procedures for designing specialized motors. Understanding these foundational principles is essential for successful motor design.

Let's suppose we are given a set of requirements and we are to design a motor that meets them. Requirements are:
3 phase synchronous, 480v, 50Hz and of hysteresis type and alnico is the only available option and it should deliver a 0.6N.m output torque.

Dimensions should not exceed 150 mm and air gap should not be smaller that 0.5 mm.

Where to start the design? What should be the initial values to start with and are there any references that can give these typical values that later on will be tuned during the design steps? Is there any reference that offers a procedure for design of special motors like the one in question?

If there are good books and references that you know of please let me know.

Cordialy,

If the supply system is a three phase system then a rotating magnetic field will be created in the air gap. The rotor will behave as an induction motor with solid steel rotor.

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
