A motor is an electromagnetic device that converts transmits electrical energy according to the law of electromagnetic induction. In order to use the motor well, it is necessary to understand the common starting method of the motor, the permanent magnet motor manufacturer will introduce the relevant knowledge to you today.


The more commonly used starting modes of the motor are: vacuum starting, soft starting, frequency conversion starting. The main advantages disadvantages between them are:


Vacuum start, the common star-triangle start, the disadvantage is that the starting torque is small, only suitable for no-load light load start. The advantage is that the price is cheap. Soft start, you can set the start time initial starting torque to achieve soft start soft stop of the equipment, can limit the starting current, the price is moderate. Frequency conversion start, can start smoothly according to the set time, let the equipment run at the set frequency, the price is higher.


The following is a comparison of the performance principles of soft start, frequency converter vacuum start:


1, the soft starter is the combination of thyristor AC voltage regulation technology power factor control technology, through thyristor voltage regulation to achieve soft motor start, soft stop, does have speed regulation function.


2, inverter is the use of power semiconductor device on off action to convert the power frequency power supply to another frequency motor control device. Controlling motor operation by frequency conversion is a really efficient way of speed regulation with high efficiency. The inverter can achieve real soft start, soft stop efficient speed regulation.


3, the general common way of decompression starting is autogenous decompression starting Y-Δ starting, autogenous decompression starting its advantage is that the starting torque is large, when the winding tap is at 80%, the starting torque can reach 64% of the direct starting. the starting torque can be adjusted by tapping.
