Product description

Product introduction:

This 3 phase induction motor 2 pole is a three-phase full voltage starter. It has a solid state overload relay and is non-combined. In addition, it has a standard width and an extra wide housing. Its rear cooling air inlet requires ventilation space. It includes a thermistor for overtemperature protection. This is a fully enclosed fan-cooled three-phase two-pole induction motor that can be used in a wide variety of general-purpose machines such as fans, pumps, compressors, machine tools, and transportation.

Product features:

This 3 phase induction motor 2 pole uses the latest design and quality materials. It complies with the IEC standard. The motor efficiency complies with the European IEC60034 standard and the EFF1 standard. The motor has many advantages such as high efficiency, energy saving, low noise, small vibration and light weight. It is easy to operate and maintain. 3 phase induction motor 2 pole has a multi-install design. It can be fitted with movable feet (if installed) so that the junction box is on the top or on both sides. The junction box can also be repositioned to the rear of the motor if required. The motor can also be mounted vertically with the shaft facing down.

Product speed control method:

Calculate the speed of a three-phase induction motor: n = 60f(1-s)/p

1. It can be seen from the above formula that changing the power frequency f, the motor pole pair p and the slip can achieve the purpose of changing the speed. From the nature of speed control, different speed control methods are nothing more than changing the synchronous speed of the AC motor or not changing the synchronization speed. Speed control methods that do not change the synchronization speed are widely used in manufacturing machinery. Changing the synchronization speed includes stator-to-multi-speed motor, stator voltage and frequency conversion.

2. From the energy consumed by speed control, there are two types, including efficient speed control and low efficiency speed control. Efficient speed control refers to constant slip or slip loss, such as multi-speed motors, frequency control and control methods for restoring slip losses. The slip loss speed control method is inefficient, and in general, the slip loss increases as the speed range increases. If the speed range is not large, the energy loss will be very small.
