Motor Sizing Calculations

Selection ProcedureTorqueSpeedThe first step is to determine the drive mechanism for your equipment. Some examples are direct rotation, a ball screw, a belt and pulley or a rack and pinion. Along with the type of drive mechanism, you must also determine the dimensions, mass and friction coefficient, etc. that are required for the load calculation 1. Dimensions and mass (or density) of load 2. Dimensions and mass (or density) of each part 3. Friction coefficient of the sliding surface of each moving part Next you will neeOnline Service

12. ROLLING, TORQUE AND ANGULAR MOMENTUM

Torque defined in this way has meaning only with respect to a specified origin. The direction of the torque is always at right angles to the plane formed by the vectors r and F. The torque is zero if r = 0 m, F = 0 N or r is parallel or anti parallel to F. 12.4. Angular Momentum.

Rotational Motion of a Rigid Body cliffsnotes

Rotational motion is more complicated than linear motion, and only the motion of rigid bodies will be considered here. A rigid body is an object with a mass that holds a rigid shape, such as a phonograph turntable, in contrast to the sun, which is a ball of gas. Many of the equations for the mechanics of rotating objects are similar to the motion equations for linear motion.

Bearing Friction Calculation Bearing Vibration Frequency

Bearing Friction. Rolling element bearings, such as ball bearings and roller bearings, are used in equipment primarily because they support the loads inherent to the machines function at a much lower friction level than any oil film bearing, such as bronze or Babbitt.This reduces the power required to drive the equipment, lowering the initial cost of the prime mover and the energy to
