Embodiment

[0041] Such as Figure 1-5 As shown, the embodiment of the present invention provides a method for on-site drying of motors, including the following drying methods: hot air drying, short-circuit current drying, iron loss drying, copper loss drying, and load drying.

[0042] Wherein hot air drying comprises the following steps:

[0043] S1. Install a blower to blow air into a heater. The capacity of the heater is determined according to the motor specification. The motor is covered with canvas, and an exhaust hole is left. The commonly used heater is a heating wire or a steam snake. shaped tube for heating;

[0044] S2. Wait until the air is heated to 70°C-100°C before blowing into the motor to ensure that the air can flow freely through the motor.

[0045] The formula for calculating the capacity of the heater is: Where pN is the rated power of the motor to be dried.

[0046] If the motor and the rotor are dried together, in the drying process, in order to prevent the sha...

Abstract

The invention provides a method for on-site drying of a motor, and relates to the technical field of motor drying. The method comprises the following drying modes of hot air drying, short-circuit current drying, iron loss drying, copper loss drying and on-load drying. Hot air drying comprises the following steps that S1, an air blower is arranged, air is pumped into a heater, the capacity of the heater is determined according to the specification of the motor, the motor is covered with canvas, the motor is dried; and an exhaust hole is reserved; and S2, air is blown into the motor after beingheated to 70 DEG C to 100 DEG C, and it is guaranteed that the air can freely flow through the motor. Through the design of multiple drying modes, a targeted drying method can be selected according todifferent structures of the motor and different on-site conditions when the motor is dried on site, and the drying quality and efficiency are guaranteed.

Description

technical field [0001] The invention relates to the technical field of motor drying, in particular to a method for on-site drying of motors. Background technique [0002] The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor is represented by the letter M in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. , The generator is represented by the letter G in the circuit, and its main function is to convert mechanical energy into electrical energy. [0003] For now, after a long period of use, the inside of the motor is prone to moisture, which leads to a decrease in insulation performance. However, the existing methods of drying the motor still have certain defects. For example, the drying method is too simple, Lack of pertinence, and there are disadvantages of unsatisfactory efficienc...
