Electric drives are an integral part of modern society, whether in industry or the municipal sector. The principle of operation is in the conversion of electrical energy to mechanical through rotary or linear electric motors of various designs and powers. The most widespread three-phase AC motors are asynchronous or induction motors. The asynchronous electric motors can be found in all areas of life from common working machines (buzz-saw, cement mixer, pumping devices), lifting equipment (lifts, cranes), to demanding industrial applications (combustion fans, extruders, conveyors, etc.).

With the arrival of automation and environmental responsibility, more and more emphasis has been placed on the start and control of electric motors, and electric drives as a whole. By proper tuning of the electric drive, the energy entering the process can be saved to a minimum, thus reducing the operating costs and, last but not least, the environmental impact.

Starting and stopping the asynchronous electric motor

DOL – (Direct On Line) starter connects the motor directly to the main supply line
Y/D – Star-delta electric motor starts the motor with a star connected stator winding
Soft starter starts the electric motor by controlling the effective value of the phase voltage

Soft starts Danfoss Drives VLT®

Protects processes, products and equipment with smooth motor control. Soft starting and stopping can be controlled in a number of ways depending on the application:

VLT® Soft Start Controller MCD 100 – a cost effective and extremely compact soft starter for AC motors up to 15 HP, due to a unique semiconductor design. Brochure

VLT® Compact Starter MCD 201/202 – two series of soft starters that provide a total motor starting solution for motors up to 110 kW. Brochure

VLT® Soft Starter MCD 500 – a total motor starting solution. Current transformers measure motor current and provide feedback for controlled motor ramp profiles. Brochure
