Direct start
What is a direct start?
The simplest boot method, enables direct start start in one time. The stator is connected directly to the network. The DOL many advantages: it is simple to implement, has a good starting torque and allows quick engine starting.
The following diagrams are used to supply a three-phase asynchronous motor directly on the network. The motor is controlled by a power button and a stop button, stop priority.
The power pattern is constituted mainly of a disconnector, a contactor and a thermal relay.
In the case of a low voltage control part as shown in the circuit diagram, add a transformer (mono 230V or 400V mono) and its protection.
This assembly is also equipped with LEDs (optional).
Electrical components:
motor switch.
AC contactor.
