FAQ

How to choose a Siemens inverter for a 5.5KW three-phase motor (2 pole)?

Siemens frequency conversion dedicated input / output filter, reactor, you contact us but smell it, the quality is guaranteed. We look forward to cooperation.

Old printing machine transformation, 37KW6 polar frequency motor with brake, inverter 55KW, now found running,

The frequency is too low or the brake gap is small

What is the frequency converter used to do, why some motor with the inverter?

Frequency converter is widely used in the speed regulation of AC motor.Varameter speed control technology is an important development direction of modern power transmission technology, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious.

380V 2 pole motor can use the inverter?

At the same time, the paint is thick, the best 2 times dipping Wiring with the end of the enameled wire end of the time, to use insulating materials separated better, more insurance

What is the IGBT? Our inverter IGBT fried,

Basically change the voltage, the voltage changes in accordance with the different frequencies, so that change the speed.

Inverter principle eff23

Low-voltage general-purpose inverter output voltage of 380 ~ 650V, the output power of 0.75 ~ 400kW, the operating frequency of 0 ~ 400Hz, its main circuit are used to pay straight to pay the circuit. Its control has gone through the following four generations. 1U / f = C sine pulse width modulation (SPWM) control mode is characterized by simple control circuit structure, low cost, mechanical properties of hardness is better, to meet the general requirements of the smooth transmission speed, has been in various fields in the industry Widely used. However, this control mode at low frequencies, due to the lower output voltage, the torque by the stator voltage drop is more significant, so that the maximum output torque reduction.

What are the AC motor speed control methods? What are the characteristics of each

1, the frequency converter: smooth, according to the need to adjust the speed, is the future direction of the development of AC motor; (FM) 2, star, triangular connection conversion, generally in the larger motor start star start, triangular operation, Starting current. (Magnetic pole pairs) 3, there is a two-speed, three-speed motor, an increase of the winding, the main change in the stator winding connection to change the speed. (Change the number of pole pairs) The speed of change has two factors: magnetic pole logarithm, frequency

What is the application of variable frequency speed control?

Generally used in the need for continuous speed control of the place. With the general exchange of motor than its advantages is able to continuously speed. DC motor, although also continuous speed control, but the price is expensive, the volume weight is too large.
