Servo motors can control speed with very accurate position accuracy, and can convert voltage signals into torque and speed to drive the controlled object. The rotor speed of servo motors is controlled by input signals and can react quickly. In automatic control systems, it is used as an executing element and has characteristics such as small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. Divided into two categories: DC and AC servo motors, their main feature is that there is no self rotation phenomenon when the signal voltage is zero, and the speed decreases uniformly with the increase of torque.
Conventional maintenance methods:
1. Apply appropriate lubrication to the servo motor. Lubrication is a major factor in efficiency and reliability. It is necessary to use a suitable type of lubricant with appropriate viscosity. Lubrication can reduce the damage of heat and friction to the motor. Ensure that the lubricating oil is free of any debris and observe the appropriate level of lubrication to prevent contamination or excessive bearing wear from affecting its operational ability.
2. Daily cleaning. Cleaning Siemens servo motors is a simple task and a part of daily maintenance. Keep the casing free of dust and debris, and ensure that all exhaust ports are not blocked. Try to prevent debris accumulation as much as possible according to routine procedures. And ensure that only approved chemicals and operating methods are used to clean the motor, in order to avoid damaging important internal components of the motor and causing symptoms of poor operation.
3. Appropriate cooling and voltage control. Despite proper lubrication, heat remains a concern for continuously running Siemens servo motors. Check to ensure sufficient cooling and allow for exhaust. In addition, use an oscilloscope to ensure that the motor does not receive excessive voltage, which can cause it to run poorly and experience heating problems.
4. Practice proper storage and handling. When dismantling servo motors, whether for service or storage, this is crucial. Similarly, motors packaged for shipment or storage should be handled with consideration for their functionality. This includes minimizing the presence of condensation and moisture, as well as planning for degreasing and insulation resistance. The long-term reliable operation of the motor should still be important, even when it is not currently working.
5. Heat, pollution, and vibration can all cause excessive wear on the motor and result in poor operation. These techniques, along with appropriate daily maintenance, are key to reducing these variables and extending the lifespan and functionality of the motor.
