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

In summary, the requirements for the design of a motor include it being 3 phase synchronous, 480v, 50Hz, hysteresis type, and using alnico. It should also deliver a 0.6N.m output torque with dimensions not exceeding 150 mm and an air gap not smaller than 0.5 mm. To start the design process, it is important to consider the supply system and the creation of a rotating magnetic field in the air gap. There are books and references available, such as "ELECTROMAGNETIC DESIGN OF A SOLID STEEL ROTOR MOTOR FOR DEMANDING OPERATION ENVIRONMENTS" by Tuomo Aho, that offer procedures for designing special motors like the one

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,
Omid Feyz Najafian

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.

1. What are the key components of a motor design?

The key components of a motor design include the stator, rotor, bearings, housing, and electrical connections. The stator is the stationary part of the motor that contains the windings. The rotor is the rotating part of the motor that is responsible for producing torque. Bearings support the rotation of the rotor within the stator. The housing provides protection and support for the internal components of the motor. Electrical connections allow for the flow of electricity to power the motor.

2. How do I determine the required torque and speed for a motor?

To determine the required torque and speed for a motor, you must first understand the application and the load requirements. The torque is the rotational force needed to move the load, while the speed is the number of revolutions per minute (RPM) that the motor can achieve. Factors such as the weight, size, and friction of the load will impact the required torque and speed. It is important to carefully consider all of these factors when designing a motor to ensure it can meet the given requirements.

3. What type of motor would be best for my application?

The type of motor that would be best for your application depends on several factors, including the required torque and speed, size and weight limitations, power source, and environmental conditions. Some common types of motors include DC motors, AC motors, stepper motors, and servo motors. Each has its own advantages and disadvantages, so it is important to carefully evaluate your requirements to determine the best fit for your application.

4. What are the considerations for selecting the appropriate motor size?

Selecting the appropriate motor size involves considering the required torque and speed, as well as the physical constraints of the application. It is important to choose a motor that can provide enough torque to move the load while also fitting within the allotted space. It is also important to consider the power source and available voltage to ensure the motor can operate effectively.

5. How can I ensure the motor design meets safety standards?

To ensure the motor design meets safety standards, it is important to follow industry guidelines and regulations, such as those set by the International Electrotechnical Commission (IEC) and the National Electrical Manufacturers Association (NEMA). These standards cover aspects such as electrical insulation, temperature limitations, and protection against hazards. It is also important to perform thorough testing and quality control measures during the design and manufacturing process to ensure the motor meets all safety requirements.
