Electric Linear Actuators With Integrated Safety Option


Welcome to part three of our six-part discussion on the basics of an electric linear actuator and factors to consider when purchasing an actuator. In this installment, we will cover the safety feature options within an electric actuation system.Get more news about actuator linear,you can vist our website!
Depending on the environment and duress that the actuator will be operating in and undergoing, it is wise to reinforce the actuator's stability and strength. Since TiMOTION is a vertically integrated electric actuator manufacturer, we can customize these features to customers' needs. Some safety feature options to consider are:
A. Overload Clutch
The overload clutch is a built-in device that slips when the electric actuator reaches a pre-set load limit. The overload clutch connects and disconnects the motor from the lead screw. This slippage prevents the linear actuator from incurring possible damage. The overload clutch is a great safety feature option on our MA1 industrial linear actuator.
B. PTC Thermistor
A PTC Thermistor essentially acts as a fuse that cuts the motor's power, protecting the motor from overheating and burning out. Our electric motors have a UL certification option with a PTC Thermistor installed inside. For over a century, Underwriter Laboratories (UL) has been a world leader in product safety and certification to nationally recognized safety and suitability standards. TiMOTION ensures our products go through proper outside testing to receive UL certification.
C. Safety Nut
A safety nut is a metal-reinforced acme drive nut used to help the linear actuator support a higher load. A safety nut is recommended for loads of 6,000N or more. TiMOTION's durable electric linear actuators also can add this feature to ensure the actuator's strength and integrity.
D. Push-Only Nut
A standard drive nut will have threads to screw into the extension tube, whereas a “push only” nut won’t have threads. This prevents obstructions (animals, people, other furniture, etc.) from being damaged by a retracting linear actuator system. An example of where this can be helpful is a recliner. If the recliner's foot is going from an extended to a retracted position and there is an object below the chair's feet, the chair's foot will not continue to push force on the object with which it comes into contact. Our TA5L, TA5P, TA6, and TA14 indoor linear actuators would be used in this sort of application.
E. Quick Release
The quick-release is a handle or cable that allows the actuator to be swiftly back-driven when released. The quick-release is designed mainly for medical bed applications when the backrest of a medical bed needs to be quickly laid flat (in case of emergency CPR). Our medically certified linear actuators can come with this option (subject to application needs) seen in our TA31 and TA15 models.
