Linear actuator motors are commonly used in a wide range of applications and processes in factory automation, packaging, medical devices, etc. The advantage of using linear actuator motors over hydraulic or pneumatic actuators is that they offer control over position, speed, and force throughout the range of motion and consume less energy. Further, linear actuator motors run cleaner and produce less noise as compared to hydraulic or pneumatic actuators, have less downtime, and are more reliable.
Linear actuator motors have various important parameters that must be measured when the motor is manufactured to ensure optimum performance. Testing motors help the manufacturer to determine that the manufactured motors conform to the specified performance parameters and are free from any manufacturing defects. Depending on the linear actuator motor type, a vast suite of tests is available right from load-speed characteristics, hysteresis tests, which is common for almost all types of motors, to specific types of tests which are applicable only to a particular motor type. Some of the important parameters measured are pull-in torque, pull-out torque, linear travel, force, speed, etc.
