Fanuc pulse coder manuals: servo driver, also known as servo amplifier, is a controller used to control servo motor. Its function is similar to that of frequency converter acting on ordinary AC motor. It belongs to a part of servo system and is mainly used in high-precision positioning system Generally, the servo motor is controlled by position, speed and torque.
1. For small power FANUC servo motor, when the heat dissipation capacity of the shell is sufficient, it can be cooled without fan.
2. Servo is generally a low-power FANUC spindle motor. If it is hundreds of watts, there is no need for a fan.
Test whether the temperature of FANUC AC servo motor is 150 degrees. If so, check the rationality of use If not, check whether there is a problem with the temperature sensor. If so, replace the temperature sensor or change the driver parameters to shield the alarm.
Under normal room temperature, the operating temperature of FANUC AC spindle motor is between 70 and 90 degrees Motor heating is a normal phenomenon. As long as it does not exceed the rated temperature, there is no need to worry The allowable temperature of FANUC DC servo motor depends on the insulation conditions inside the motor.
The method to remove the FANUC linear motor on the CPU fan is as follows: uncover the label. There is a rubber ring below. Lift it with a needle to see the shaft of the motor. There is a snap ring on it. Take the needle to remove it and you can see the inside of the motor.

1. Because there are many kinds of FANUC spindle motor fans, not all fan motors can be disassembled smoothly. For example, integrated fans and motors fixed with glue can only be demolished destructively
2. Some FANUC spindle motor cooling fans use two-phase motors with various control circuits. There may be integrated drive chips, built-in Hall sensors, detection of motor running position, automatic commutation, PWM speed regulation and speed feedback, so it will be more complex.
Remove the mesh cover first, and then remove the front pin cover and fan blade. Generally, oil can be dropped into the bearing at this time If the effect is not good, loosen the four screws on the mounting surface, and then pry open the rear cover with a slotted screwdriver (there are generally four rubber buckles between the rear cover and the mounting surface). After opening, remove the motor, clean it, refuel it, and then install it in reverse order. However, pay attention to adjustment during installation of FANUC servo drive, otherwise the gap is uneven and cannot rotate. Power on the motor after installation, and install the rubber housing after adjustment.
