MX341 brushless  avr automatic voltage regulator 
The MX341 is a 2 phase sensed Automatic Voltage Regulator and forms part of the excitation system for a brushless generator. In addition to regulating the generator voltage, the AVR circuitry includes protective features to ensure safe reliable control of the generator. This model supercedes the Series 3 range (same footprint & wiring 1 extra terminal) This AVR is used only in conjunction with permenant magnetic type alternators. Excitation power is resulting from a three-phase permanent magnet generator(PMG), to isolated the AVR power circuits from the effects of nonlinear loads and to reduce radio frequency interference on the generator terminals, constant generator short circuit current is another feature of the PMG system.

The AVR senses the voltage in the central generator winding and controls the power fed to the exciter stator and hence the main rotor to keep the generator output voltage within the specified limits, compensating for load, speed, temperature and power factor of the generator.

Soft start circuitry is included to provide a even controlled build up of generator output voltage.

A coffee grinder with a cone-knife grinder places a conical knife disk at the bottom of the machine, and then cooperates with the outer ring knife disk for grinding. The coffee powder produced in this way will be closer to granular, and at the same time, the water absorption path of the coffee particles will become longer, and it will take more time for the inside to contact the water, which will result in the coffee powder being released within the first time. The soluble substances are less, and the concentration will not be too high in a short time.
