The service life of the linear stepper motor depends on the service life of motor and ball screw transmission part of the loss, fitting precision and quality in the market. Under normal circumstances, the linear motor can be controlled through type complete, up to 20 million times of operation cycle and carrying nut drive motor control can provide the operating life of 25000 hours. Motor final fatigue and integrated life is decided by each user's specific application. Continuously: continuous operation under the rated voltage motor. 25% duty: on the L/R drive to twice the rated voltage of motor operation, motor power time is approximately 25%. Motor output torque than running under the rated voltage is about more than 60%. Note that the cycle time has nothing to do with the load on the motor. Life: the life of the linear motor can under the specified load for the motor sports, and maintain precision stepper cycles. The life of the rotating machine to work hours a movement cycle: a linear motor cycle including stretched out and back to the initial position of the whole movement. About how to choose the appropriate motor and make sure that it has the longest life, here are some general guidelines, but in the end, if you want to in for a given system determine the performance of step motor, the best under the 'site conditions', or at the scene of the as similar as possible under the conditions of the assembly test. Resulting from stepping motor without brush wear, since life is usually more than other mechanical parts in the system and step motor if failure, usually due to some mechanical parts, which is caused by the failure of the screw/nut joint and the bearing is first will produce fatigue failure of the parts, and work or thrust and torque working environment will affect the service life of these parts. If the motor rated torque or thrust, thrust, or close to its rated torque or its longevity will be affected, transport control test showed that motor life and exponentially increases with the decreasing of the workload, in general, the bearing capacity of the motor should be designed in its biggest - 40%60%, some environmental factors, such as high humidity, exposure to the caustic chemicals, a lot of dirt as well as the quantity of heat, can affect the service life of the motor, the assembly of some mechanical factors, such as linear motor axis of lateral load or unbalanced load of rotating machine, the installation process of different heart, or frequent positive and negative to no deceleration process, will cause adverse effect to motor life. If use motor under short work, and applying high voltage to the motor, the polarization time shall guarantee that the motor temperature rise shall not exceed the maximum temperature rise limit, if the motor power do not have enough time, will generate too much heat, and winding overheating, eventually led to the motor failure. Design one of these factors can be reduced to the smallest system will ensure that the motor's biggest life, will be life to maximize the first step is to choose a safety factor of 2 or more motor, the second step is by the lateral load, unbalanced load and impact load to reduce to a minimum to ensure that the coefficient has a good mechanical performance, in addition, the system should be equipped with cooling system, if the system exists in the caustic chemicals, motor and all other parts must be treated in protection, finally, under the condition on site testing machine and its components to ensure proper application. If comply with these guidelines, linear motor control, will be in a wide range of areas to provide you with reliable operation. If users need help on the design, the accused will help you to gain the longest in our motor life and the best performance. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
