The invention relates to a manufacturing method for a high-speed permanent magnetic rotor. By performing the processes of assembling, polishing, dynamic balance and the like, and setting reasonable parameters, it can be ensured that magnetic poles of the motor rotor are firmly bonded on a rotor iron core at a high speed of 40,000 rpm. The permanent magnetic rotor manufactured with the method can work under a condition that the rotational speed is 50,000 rpm for a long term, is successfully applied to power motors of digital electronic control systems of aircraftengines, and meets operating requirements of high rotational speeds of aviation motors.

The invention discloses a railway carriage watering measuring control system device and a method for metering and monitoring watering. The system comprises m numbered remote control units, n numbered sets of on-site hosts and one set of computer management systems, wherein n is an integer between 1 and 1000, and m is less than or equal to n; each set of on-site hosts comprises an electronic control system and a pipeline system, and the on-site host electronic control system comprises a monitoring center, a flow acquisition unit, a solenoid valve control unit, a data storage unit, a data transmission unit, a wireless data transmission unit, a state indication unit and a voltage-stabilizing power supply unit. The computer management system and each on-site host carry out on-site data transmission by a transmission path. The method for metering and monitoring watering utilizes the system of the invention and adopts remote control software, on-site host software and computer management system software, and a watering operator sends out a specified instruction for switching on or off of a watering plug by a remote control unit so as to realize the purposes of remotely controlling the switching on and off of the watering plug and automatically recording and accurately metering watering flow.

The invention provides a permanent magnet energy-saving electronic automatic gearbox. The permanent magnet energy-saving electronic automatic gearbox mainly comprises an engine, a motor shaft, a magnetic isolation assembly, a conductor rotor, a steel body, a copper conductor ring, a permanent magnet rotor, a permanent magnet ring, a spline, an electronic control system, a liquid inlet piston and the like. The electronic control system can control the spline and the magnetism isolating assembly at the same time, so that the spline and the magnetism isolating assembly move cooperatively, and a better speed changing effect is achieved. According to the invention, the engine side is connected with the permanent magnet rotor, the conventional mechanical connection transmission between a motor and a load is replaced by an air gap torque transmission mode, and a load protection function is realized. The device is of a pure mechanical structure, pollution such as harmonic waves and electromagnetic interference is avoided, and the device is an environment-friendly product. Buffer starting and multiple times of starting can be achieved. The magnetic isolation assembly is used in cooperationwith the spline, the magnetic moment can be rapidly adjusted, and the speed adjusting effect is better.
