The frequency conversion method compared with other control methods. A small startup current start torque; speed continuously adjustable speed. The torque. The current control precision; operation. High safety. To facilitate remote control; high power factor. The advantages of harmonic effect.
The characteristics of frequency converter drive: 1 small starting current can be adjusted continuously, 2 speed, 3 to use standard motors, 4 maximum speed is not affected by the impact of power supply, motor speed can be 5. 6 small, easy explosion, 7 low speed torque characteristics and adjustable speed and mode can be set to 8 or 9, you can use the cage type asynchronous motor.
The effect of frequency converter drive: 1 power equipment capacity decreases, 2 easy to choose the best speed. The 3 speed smooth, without changing the original design of motor 4, the maximum working capacity is not affected by the effects of power frequency, or do not need because of the frequency change design, 5 relative to the DC motor, explosion-proof electric machine has the advantages of small volume, low production cost, allowing the stall 6 low speed motor in a short period of time, 7 for the process requirements, and speed control, do not need to maintain the motor 8.
Application Research of inverter drive: 1 compressors, pumps, fans, conveyors, machine, mixer, air conditioning, grinders, chemical machinery, transport machinery, tablet machinery factory, chemical plant, coal mine, transportation machinery, vehicle production line.
Main applications: 1 inverter air conditioner, machine, mixer, textile machinery factory, tea machine, spindle drive, machine production line, vehicle transmission, metal processing machinery, handling machinery, textile machinery, all kinds of handling machinery, blower, pump, mixer, extruding machine, spinning machine.
The main application method of frequency converter: 1 using the compressor running speed, continuous temperature control, optimal operation speed of 2 selected continuously, 3 to replace the DC motor, using high-frequency motor running in high speed, the growth rate of 5 since the start of operation, eliminate or buffer stop, caused by the bad, more than and 6 motors with proportional speed, linkage operation, synchronization 7 operation, running speed, the power frequency power by inverter in constant speed operation and operation combination.
The main application of the original converter: 1 by the power supply on-off control with constant speed operation. 2 power supply, 3 DC motor, 4.M-G device, 5 with constant speed frequency power, stator voltage control, 6 mechanical transmission reducer, stator voltage control, electromagnetic slip away from full control, 7 power supply constant speed operation, a baffle, valve control, mechanical drive, hydraulic coupling.
