Reasons and preventive measures for load on Rack&Pinion pneumatic actuators

Load is a common issue in the operation of Rack&Pinion  pneumatic actuators. What are the reasons for the occurrence of load in Rack&Pinion Pneumatic Actuators? How can Rack&Pinion Pneumatic Actuators prevent this problem?

1. The high ambient temperature during use leads to a relative decrease in the thermal capacity of the motor.

2. The setting value of the torque limiting mechanism is incorrect, and the stopped torque is less than its setting value, resulting in continuous excessive torque and causing the motor to stop rotating.

3. The voltage of the power supply is too low to obtain the required torque, causing the motor to stop rotating.

4. Due to some reasons, the torque limiting mechanism circuit malfunctioned, resulting in excessive torque.

5. Continuous use generates heat accumulation exceeding the allowable temperature rise of the motor.

Generally, when running within a predetermined time, the motor will not experience overload. The main protective measures for Pneumatic Actuators under load conditions are as follows:
1. Protecting the motor from stalling by using a thermal relay.
 
2. Short circuit accidents can be effectively avoided by using fuses or overcurrent relays.
 
3. Protect the motor from overload caused by continuous operation or electric operation by using a thermostat.
 
In summary, the reasons and preventive measures for the load of Rack&Pinion  pneumatic actuators  are as follows.
