What is a Switched Reluctance Motor?

 Switched reluctance motor is a type of speed-regulating motor developed after DC motor and brushless DC motor. Product power levels range from several watts to hundreds of kilowatts, and are widely used in household appliances, aviation, aerospace, electronics, machinery, and electric vehicles.

The switched reluctance motor (SRM) used in the switched reluctance motor speed control system is the part that realizes the electromechanical energy conversion in the SRD, and it is also the main sign that SRD is different from other motor drive systems. SRM series double salient pole variable reluctance motor, the salient poles of the stator and rotor are laminated by ordinary silicon steel sheets. The rotor has neither windings nor permanent magnets. Concentrated windings are wound on the stator poles. The two diametrically opposed windings are connected together, which is called "one-phase". SR motors can be designed with a variety of different phase numbers. The stator and rotor There are many different combinations of poles. The large number of phases and small step angle are beneficial to reduce torque ripple, but the structure is complex, and the main switching devices are large, and the cost is high. Nowadays, four-phase (8/6) structure and six-phase (12/8) are more commonly used)structure.

ADS1262 ADC: Feature, Pinout and Datasheet

Image
Description : The  ADS1262  is low-noise, low-drift, 38.4-kSPS, delta-sigma (ΔΣ) ADCs with an integrated PGA, reference, and internal fault monitors. The ADS1262 integrates an auxiliary, 24-bit, ΔΣ ADC intended for background measurements. The sensor-ready ADCs provide complete, highaccuracy, one-chip measurement solutions for the most-demanding sensor applications, including weigh scales, strain-gauge sensors, thermocouples, and resistance temperature devices (RTD). The ADCs are comprised of a low-noise, CMOS PGA (gains 1 to 32), a ΔΣ modulator, followed by a programmable digital filter. The flexible analog frontend (AFE) incorporates two sensor-excitation current sources suitable for direct RTD measurement. A single-cycle settling digital filter maximizes multipleinput conversion throughput, while providing 130-dB rejection of 50-Hz and 60-Hz line cycle interference. The ADS1262 is pin and functional compatible. These devices are available in a 28-pin TSSOP package and are fully s

Homemade air variable capacitor

What is an air variable capacitor? In some applications, a capacitor is required to provide a variable capacitance value. Variable capacitors are used in such cases. They allow the capacitance value to be changed repeatedly mechanically and electronically. Air variable capacitors use air as a dielectric and are composed of two sets of metal sheets, one of which is fixed and the other can be rotated. The metal plates are arranged in a network. The overlap between the two sets of metal plates can be adjusted by rotating the moving plate, and the capacitance changes accordingly. But the air gap remains the same. Application of air variable capacitor Due to its simple design and powerful functions, air variable capacitors are widely used. Its most important use is in the radiofrequency field, for example, to tune a radio by setting a resonance frequency. They are also important components of radiofrequency matching networks, magnetic resonance imaging (MRI) equipment, and precision
