YD series 2 speed 3 phase motor is one of the main series products deriving from three-phase series. The motor can change rotational speed to meet the requirements of load state, so that they can properly match the demands of power and simplify adjustments speed system. They are widely used in such industrial and agricultural departments, as machine tools, mining metallurgy, spinning and weaving, printing and dyeing, chemical industry and agricultural machine. YD motor is equivalent to other foreign advanced machines, and therefore they are matching with single-machine or machine for export as well as motors for similar types imported from abroad.

About the soft start mode of the motor
We need to know what is the soft start of the motor. Motor soft start is to use a soft starter connected in series between the power supply and the controlled motor to control the conduction angle of its internal thyristor, so that the motor input voltage gradually rises from zero in a preset function relationship, until the end of the start, giving the motor full The voltage is soft start. During the soft start, the starting torque of the motor gradually increases, and the speed also gradually increases.
Soft start is generally divided into the following ways:
1. Step start
Turn on, that is, in the shortest time, make the starting current quickly reach the set value, which is a step start. By adjusting the starting current setting value, a quick starting effect can be achieved.
2. Pulse shock start
In the starting stage, let the thyristor turn on with a relatively large current for a short period of time and then fall back, and then linearly increase according to the original set value, and then connect to constant current start. This starting method is rarely used in general loads, and is suitable for starting occasions with heavy loads and large static friction that needs to be overcome.
