If, ball bearing screw in the process of acceleration and deceleration , a short play high current needs, you must be active in the planning stages of thinking equivalent thrust , depending on the actual needs , adding cease activity time . Else if the motor current is continuously pushing things matter more than the continuous current , but also dependable overheating problems . So the system in planning activities necessary when thinking about the layout of the motor heat dissipation characteristics . Lead offset preloading essentials : ( increase pitch or pitch out )
Features: on the pitch for the nut offset δ values to replace the traditional double nut preload essentials , the essentials and more practical in the light preload , the best plan in the pre- pressure dynamic load of 5% or less. Tensile preload essentials features : the use of a pre- thick tablet will arrive two nuts outside the sheets essentials preload results , this is the most common use of the ball screw essentials . Features : the thin film preload , then screw nut bolt two together , to reach the pre- pressure of the results.
Ball control fundamentally similar essentials , such acceptance pulse controlled, active control card is still sent to the drive pulse , the other situation or if the current situation is the speed (or torque or strength situation ) by the same active controller sends voltage to the drive. Difference is that control linear motor, will not need to have complicated conversion strategy , gear ratio strategy , just directly to the activities tend to consider the isolation , strategy can be, but also directly with the activities set acceleration and speed that is biased available . Individually any motor problems accompanied by fever , we must think in the planning stages of this problem , fever tension from acceleration and deceleration , if the acceleration and deceleration are maintained at the current required to drive the motor and under continuous current , there will be no tension heating problem .
