• Torque - Relevant for Toolholding?
  of a tower clock: Assuming the one meter long hand of a tower clock weighs so much that there would be a force of 10 kilograms at the end, there would be a torque of 100 Nm at the center of the clock. Calculation (simplified): F = 10 kg = 100 N. l = 1 Meter. M = F * l = 100 N * 1 m = 100 Nm. The clock...
• Sorting out shaft connections
  Motors and gearboxes that generate high torque and acceleration may make shaft keys obsolete. Designers should analyze stresses and backlash when weighing keyed versus keyless shafts. Stresses in the keyway are critical in evaluating the shaft's torque capacity. Opposing forces exerted by the shaft...

Form factor is an indication of how well AC. a further calculation determines the. with the following formula: power is converted to DC. horsepower of the input motor required...
• Motor Type Selection
  for. motor acceleration must be included in the calculation of the operating points: MMot, = Jrot · /30 ·. nMot/t (duration t, rotor moment of inertia Jrot). The effective load must then be recalculated. There are influences on the rated torque. Take, for example, the rated torque in a maxon motor. MN...
• Selecting Dc Brush and Brushless Motors
  . In highly dynamic applications, the additional torque needed for motor acceleration must be included in the calculation of the operating points: MMotα • (π/30) • (ΔnMot/Δtα ). where Δtα = time duration and Jrot = rotor moment of inertia. The effective load must then be recalculated. Some motor...
• Optimally Transferred
  pressure is reduced by special designs of the seals. The opening and closing force is thereby balanced, so that the faces are always lubricated. This does not only reduce wear, but also the starting torque and the heat generation in the gap due to reduced friction. In order to achieve the required...
• Metrically measured motions
  with metric, it's important for engineers to keep units straight for calculations of mass, force, and torque. Manufacturer catalogs list most leadscrew efficiencies, but engineers must know what efficiency an application needs. Whether millimeter or inch, forward torque is always positive, while...
• New rules for sizing servos
  in large torques due to system inertia. If e-stop torque is not listed in the catalog, be sure to ask the supplier the allowable torque and how many times it can be applied to the gearbox before teeth break. If a coupling connects the gearbox and load, then a bearing-life calculation is unnecessary...
