High-power servo motor is one of the accessories for driving and running in mechanical equipment. The servo drive usually consists of two units: a controller and a power amplifier, which track the motion control instructions of the upper computer in real time; the servo motor is controlled by position, speed, torque, etc. In order to achieve high-precision positioning of the transmission system. Some customers and friends mentioned that the temperature of the equipment is very high during use. If it is used normally, the high-power servo motor will not have such a problem, so what is the reason for the high temperature of the high-power servo during use?
1: Is it used for continuous operation? The characteristics of high-power servo motors are not suitable for continuous operation. In this case, there will be a higher temperature rise. Please reconfirm the mechanical action requirements and re-evaluate the motor used.
2: Please confirm the frequency and period of organizational action. If the frequency of operation and stop is too high, the pulse input stops for too short a time, which may cause the current to be reactivated before the drop, so the temperature rise at this time will be higher. High-power brushless DC servo motors suggest that you can reduce the operating frequency to increase the temperature rise.
3: Can the operating current be reduced to improve? When the torque is large enough, the temperature rise can be effectively reduced by reducing the operating current of the drive. However, if a large current must be used due to torque, it is recommended that you replace the high-power servo motor with a higher-level motor, and then reduce the current to increase the temperature rise.
4: Can it be improved by reducing the operating current? When the holding force is large enough, adjusting the current of the drive can effectively reduce the temperature rise when the motor stops. However, due to the stop holding force, a larger stop current must be used. It is recommended that you replace the high-power servo motor with a higher-level motor, and then reduce the current to increase the temperature rise.
5: What is the ambient temperature? Is it too high? Motor temperature = ambient temperature The motor temperature rises, so when the ambient temperature is higher, the motor temperature will also be higher. Professionals recommend installing cooling panels or cooling fans to help dissipate heat.
6: Please confirm whether the motor terminal wiring is correct? Incorrect phase connection will cause the jitter phenomenon of poor motor operation, and may also cause the problem of high temperature rise.
