First, what is a straight-flow motor? A direct-flow motor is a device for the movement of the direct-flow motor speed, which, because the direct-flow motor has the characteristics of a low-turn dynamic rectangular and cannot be replaced by a communication motor, is the device for the movement of the direct-flow motor speed, which has a wide application of six。
Ii. On what occasion is the use of a straight-flow modem selected
1. Broader speed planning。
2. A dynamic response process with faster demand。
3. Add an automatic smooth transition process at a slower pace。
4. The need for low-speed operations is high。
5. A better demand for excavator characteristics allows the automatic restriction of overloading to be limited to the specified current. The above five points are also characteristic of the use of straight-flow speed adjusters。
Iii. Direct current speed adjuster applications:
Direct-flow fixers are widely used in the fields of digitally controlled machine beds, paper printing, textile printing, fibre-optic cable equipment, packaging machinery, electrical machinery, food processing machinery, rubber machinery, biological equipment, printing circuit board equipment, experimental equipment, welding and welding, light engineering machinery, logistics delivery equipment, locomotive vehicles, medical equipment, communications equipment, radar equipment and satellite ground acceptance systems。
A brief description of the principles of the direct-flow speed adjuster operation:
Direct-flow modems are the equipment for the movement of the direct-flow motor speed, up-end and communication power links, down-end and direct-flow motor links, which converts the communication power into a two-way output direct-flow power source, enters it all the way to the direct-flow electric power plant accelerator (trono), enters it all the way to the direct-flow electric power hub (twirl), and direct-flow modems are controlled by the direct-flow voltage power of the control hub to control the direct-flow motor transfer. A direct current motor is used to provide a resonance current to the motor, which is used to determine the rate of rotation of the direct current on the basis of the resonance current and to modify the output of the power hub, if necessary, in order to re-pace the power。
V. Quickening programme for direct currents
In general, there are three methods: one, to modify the power-centre voltage; two, to modify the magnetic voltage voltage; and three, to modify the circuital resistance of the power-centre. It's quite common to retrench the speed system, i. E. 1.
Vi. A modular straight-flower switcher, which collects the power, controls, drives the circuit in one form, selects a stereostructure layout, controls the selection of the circuits using micropower-consuming elements, completes the current with a pv coupling, isolates the voltage, and adjusts the ratio constants of the circuits, the fraction constants and the differential constants with a pid adaptor. It is small in size and light in size and can be used separately or can be installed directly on a direct current generator to form an integrated straight-flow motor and to have all the functions that the speedr should have。
