Three-Phase Asynchronous Direct Online Motor Connected to Hydraulic Pump

In this example, an asynchronous motor is connected to an ideal pump. The diameter of the valve on the hydraulic system affects the speed and current drawn by the motor.

At 0 seconds, the motor is at zero speed. It starts up and at 2.5 seconds, it reaches rated speed. At 9 seconds, the diameter of the valve reduces to 4cm and the motor stalls.
