DD motor with double bearing structure, bearing can affect the DD motor force, axial pendulum as a whole and the deflection of the radial, so bearing of life how to calculate? According to the GBT - 63912010 rolling bearing dynamic load rating and the rated life, simple calculation of rolling bearing life: L10: basic rated life, millions of transfer; Ca: axial basic dynamic load rating, Pa: axial equivalent dynamic load, case: load calculated according to 500 kg, final computation results for 82 billion turn, turn assumes that the motor according to top speed of 100 RPM, conversion grown, the results for 1560. 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.
