"MITSUBISHI inverter FR-E720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.75KW.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency, the device is the first power of the AC power conversion to DC (DC), the process is called rectification.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter) FR-F840-01160-2-60
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter.
Inverter output waveform is simulated sine wave, mainly used in three-phase asynchronous motor speed control, and also called frequency governor. "MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 5.5KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%).
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
The inverter drive can be smoothly start (start time longer).
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load. Motor series: medium inertia, medium capacity.
Using a serial absolute / incremental encoder.
Rated output power: 3.5kw.
Rated speed: 3000rpm.
With the brake: without.
Shaft end: straight shaft.
When the AC servo motor has no control voltage, only the pulsating magnetic field generated by the excitation winding is generated in the stator, and the rotor is still not moving.
When the control voltage is controlled, a rotating magnetic field is generated in the stator, and the rotor rotates in the direction of the rotating magnetic field,
In the case of constant load, the speed of the motor varies with the size of the control voltage,
When the phase of the control voltage is reversed, the servo motor will reverse.
