Embodiment Construction

[0010] As shown in Figure 2, the construction method of the synchronous generator and synchronous motor mutual feed system, select two synchronous motors GS1 and GS2 with the same performance parameters (such as number of poles, rated voltage, etc.), and make one of the synchronous motors GS1 The stator can rotate relative to the rotor. The conventional method is to make the synchronous motor a biaxial extension and support the biaxial extension through the bearing; keep the mechanical phase of the rotor of the two synchronous motors (that is, the mechanical position of the rotor relative to the stator) the same In the case of coaxial connection; a motor M is coaxially connected with two synchronous motors (the motor M can be located on one side of a synchronous motor or between two synchronous motors. From the perspective of structural rationality, the motor M is usually located in a synchronous motor. One side of the synchronous motor); start the motor M to drive the two sync...

Abstract

The invention relates to a motor linkage technology, in particular to a construction method of mutual feedback system of synchronous generators and synchronous motors, which aims to solve the problems that the existing reducer power-load testing system has high cost and wastes energy. The invention has the following steps: two synchronous motors with the same performance parameters are chosen and then a stator of one motor can rotate relative to a rotor; the two synchronous motors are connected coaxially on the condition that the mechanical phases of the rotors are maintained the same; an electric motor is connected coaxially with the two synchronous motors; the armature outputs of the two synchronous motors are connected through the same phase, and then the angle of one synchronous motor stator is artificially rotated, and the rotated synchronous motor is operated in a state of the generator or the electric motor, while the other synchronous motor is operated in a state of the electric motor or the generator. The testing system constructed with the method is low-cost and energy-saving, and is applicable to the performance testing of reducers, synchronous motors, shafts, torque sensors, electric appliances, cables, and switch devices.

Description

technical field [0001] The invention relates to motor linkage technology, in particular to a construction method of a synchronous generator and a synchronous motor mutual feed system. Background technique [0002] After the reducer (device) is manufactured, a power-load test is required. During the test, connect the low-speed shaft ends of the two reducers JS1 and JS2, and then use a DC (speed-regulating) motor DG (or an AC motor with a speed-regulating device) to drive, and at the same time connect a generator to the output shaft end of the reducer. The generator FG (as a reducer load), and the voltage (electric power) output terminal of the generator is connected to a (group) electric load (resistance R) (as shown in Figure 1). If the tested reducer wants to run at full load, it needs to be driven by a high-power DC motor or an AC motor with a speed regulating device, and a high-power generator is required as a load; and the manufacture of a high-power motor and its contr...
