Problems solved by technology

Since the brake still has a certain resistance after it is powered on and released, using the traditional assembly process will lead to a large error in the positioning of the motor rotor when the motor and encoder are assembled together, resulting in the zero point of the encoder relative to the magnetic field of the motor rotor. The positioning of the steel position will produce a large error

Embodiment Construction

[0022] Below, further description will be made in conjunction with the accompanying drawings and the preferred embodiment.

[0023] like figure 1 As shown, by adjusting the installation position and order of the brake and the encoder on the motor body, the positioning accuracy of the zero point of the encoder relative to the magnetic steel position of the motor rotor is improved.

[0024] (1) Press-fit the stator winding into the motor casing; press-fit the front bearing of the motor rotor into the bearing chamber of the front end cover, at this time, the motor rotor passes through the stator winding; install the front end cover of the motor; install the rear end cover of the motor; Complete the installation of stator winding, rotor, front end cover and rear end cover first;

[0025] (2) Then connect the stator winding with 5V DC, in which the U phase of the stator winding is connected to the positive pole of the power supply, and the V and W phases are connected to the negat...

Abstract

The invention discloses an alternating current servo motor assembly process with a brake. The process comprises the following steps: firstly mounting a stator winding, a rotor, a front end cover and a rear end cover; passing direct current through the stator winding; finding an actual zero point of an encoder by using an encoder zero point detector; mounting the encoder in a motor rear cover; passing the direct current through the brake, opening a band-type brake and mounting the brake in a brake shell to finish the assembly. According to the process, the assembly accuracy for assembling the encoder on the motor can be effectively improved. The process relates to the technical field of motors.

Description

technical field [0001] The invention relates to a punching sheet for a motor, and more particularly relates to an assembly process of an AC servo motor with a brake. It belongs to the field of electric motors. Background technique [0002] AC servo motors have been widely used in machine tools, printing equipment, packaging equipment, textile equipment, robots, automated production lines, etc. due to their high positioning accuracy, stable speed, and strong overload capacity. relatively high industry. [0003] In a complete servo system, high positioning accuracy is one of the important features. Factors affecting positioning accuracy include the control accuracy of the drive, the feedback accuracy of the encoder, and the assembly accuracy of the encoder on the motor. [0004] In order to meet the practical requirements, the existing servo motors are mostly equipped with power-off brakes, which are generally installed between the motor body and the encoder. Since the brak...
