Overview

Essential details：PCIe-6734 NI Multifunctional I/O equipment

4-way AI (16-bit, 3.5 MS/s/ch), 2-way AO, 24-way DIO, multi-function I/O device – PCIe 6374 is a synchronous sampling multi-function DAQ device. The module provides analog I/O, digital I/O, four 32-bit counters, and analog and digital triggers. Onboard NI‑STC3 timing and synchronization technology provides advanced timing capabilities, including independent analog and digital timing engines and re-triggering measurement tasks. PCIe 6374 is suitable for many applications, such as IF digitization; Instantaneous recording; ISDN, ADSL and POTS manufacturing tests for the communications industry; Ultrasonic and sonar testing and high energy physics. The included DAQExpress™ companion software provides basic measurement and analysis, while the NI‑DAQmx driver can be used to create custom automated measurement and control applications.

PCIe-6734 NI Multifunctional I/O equipment

When the synchronous motor works, the three-phase symmetrical current is passed into the stator’s three-phase winding and the DC current is passed into the rotor’s excitation winding. When the three-phase alternating current is passed into the stator three-phase symmetrical winding, a rotating magnetic field will be generated in the air gap. When DC current is passed through the rotor field winding, a stationary magnetic field with constant polarity is generated. If the pole number of the rotor magnetic field is equal to the pole number of the stator magnetic field, the rotor magnetic field rotates synchronously with the stator rotating magnetic field due to the magnetic tension of the stator magnetic field, that is, the rotor rotates at the speed and direction equivalent to the rotating magnetic field, which is the basic working principle of the synchronous motor.
Mode of operation
There are three main modes of operation of synchronous motors, that is, as generators, motors and compensators.
Running as a generator is the most important operation mode of synchronous motor.
Operation as a motor is another important mode of operation of synchronous motors. The power factor of synchronous motor can be adjusted, and the application of large synchronous motor can improve the operation efficiency when speed regulation is not required. Small synchronous motor has been widely used in variable frequency speed control system.
The synchronous motor can also be connected to the power grid as a synchronous compensator. At this time, the motor does not have any mechanical load, and the inductive or capacitive reactive power required by the excitation current in the rotor is adjusted to the power grid, so as to improve the power factor of the grid or adjust the voltage of the grid.
