WebJan 11, 2024 · Synchronous speed, frequency, and poles of the induction motor are related by the formula: η sync = (120 * f e) / P η sync = Synchronous speed f e = … Webthe motor has, the slower it runs. Table 1 indicates typical synchronous speeds. The actual speed of the motor is less than its synchronous speed with the difference between the synchronous and actual speed referred to as slip. The amount of slip present is proportional to the load imposed upon the motor by the driven equipment (see Figure 4).
