The speed and intelligence of computers reflected in motors

Designers in the 1960s experienced the concept of circuit board design, but not everyone could have foreseen the rapid development of computer applications in motor design. According to statistics, designing an ordinary constant force asynchronous motor would take approximately 16 hours by hand in 1957; At that time, the application of electronic computers only required three minutes of computing time on the machine, and by 1967, the computer computing time had been shortened to half a minute. Not only has the calculation time been greatly reduced, but the calculation range of the scheme has also expanded by more than twenty times. The research results indicate that after the specific application of some optimization programs, the scheme design can achieve automatic optimization, greatly improving the quality and speed of design work. Compared with commonly designed based on experience, the optimized design of a constant force motor significantly reduces its manufacturing cost or total operating cost under the same performance indicators.

In addition to electromagnetic design programs, electronic computers are widely used in many other calculations or analytical studies closely related to motor design, such as steady-state and transient thermal calculations of motors, calculations of critical speed and bearing capacity, mechanical calculations of large components, and analysis of motor transient processes and magnetic field research.

In addition, foreign countries have begun to use electronic computers for productive drawing work, resulting in automatic design systems that automate design calculations, print output, and provide drawings.
