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.

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
