Aufgabe zum Asynchronmotor: Wie berechnet man die Kennwerte Schlupf und synchrone Drehzahl? (ASM 04)

0:53 a) Synchronous speed 3:57 b) Slip 4:37 c) Rated torque 5:50 d) Apparent power S 7:24 e) Power ratings, efficiency 8:42 f) Apparent power at 400 V 10:15 g) Reactive power The asynchronous motor is like an open book when you look at its nameplate. I will present the key values ​​shown there using a problem and explain why they are important for operation. Calculate specific key values ​​for an asynchronous motor with the nameplate shown. The values ​​sought are the synchronous speed, slip, torque, apparent power in star and delta connections, line current, power factor, active power, reactive power, and efficiency. Furthermore, the various units such as volt-amperes, watts, and volt-ampere-reactive (var) will be assigned to the respective power values. Here I also explain what to consider regarding star and delta connections when looking at voltages and calculating apparent power. It's important to know that a three-phase power supply always provides 400 V. The rating plate indicates the voltage a phase can withstand and the voltage it cannot. You'll also learn what a pole pair is, why there can be different numbers of pole pairs, and how this affects the speed of an asynchronous motor.
