Multiple Function Keyboard

The multiple-function keyboard of frequency phase inverters control the operation of the 90kw variable frequency drive inverter, such as start, stop, and acceleration. The user can press the corresponding buttons to make the 3 phase motor inverter work according to set 100 hp frequency inverter parameters or control the 3 phase inverter machine's operating speed.

Electronic Screen

The electronic screen of the 125 hp frequency inverter is a key component in the three phase inverter control system, providing users with an intuitive and real-time information display. The digital screen can monitor the operating status of the 100hp frequency inverter in real-time, including input and output voltage, frequency, and current waveform, which helps to detect abnormal conditions in time.

Rugged Casing

The variable frequency drive inverter's rugged casing plays multiple roles in its design. It is not only about protecting the circuits and internal components inside the device but also about the safety, stability, and reliability of the device. The frequency drive inverter not only protects the internal circuits and components but also provides safety protection.

FAQ

What are the three-phase inverter control techniques?

Pulse width modulation (PWM) techniques: PWM is a widely used method to control the output voltage and frequency of 3 phase variable frequency drives by adjusting the width of the pulses in a switching pattern.
Field-oriented control (FOC): FOC, also known as vector control, is a method used to control the torque and speed of three-phase AC motors (like induction and permanent magnet synchronous motors) by controlling the stator currents in a coordinate system aligned with the rotor flux.
Direct torque control (DTC): DTC is another method primarily used for controlling AC motors, particularly induction motors. Unlike FOC, DTC directly controls the motor's torque and flux without the need for coordinate transformations.

Operating temperature of frequency inverter

If I'm going to use a 7.5 hp 230v 3 phase motor and the input is 240v single phase, will the 7.5 frequency inverter be sufficient or will I need to upsize frequency inverter. It will be installed in a garage, so it will have to deal with the summer heat and cold winter ambient temperature.

Generally, make 15% oversizing. And our frequency inverter temperature range: –10℃~ +40℃; frequency inverter will be derated if ambient temperature exceeds 40℃; each rise 1℃, the derate will be 5%.
