Motor Installation Labor Calculator at 14% installation handling allowance: a worked example

Push installation handling allowance up to 14% and the picture changes. This example computes every intermediate figure at that operating point. a manufacturing engineer needs labor hours for motor or fan installation work content

The inputs for this scenario

  • Motors or fan assemblies installed: 2,400 motors (unchanged)
  • Motor installation rate: 4.5 motors / min (unchanged)
  • Installation handling allowance: 14 % (raised for this scenario; the documented default is 12)

Working through the calculation

  • Applying the documented formula (Base motor installation time = motors or fan assemblies installed รท motor installation rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 608 hr for required motor installation labor, the number this scenario is built around.
  • At this operating point the engine returns 533 hr for base motor installation time.
  • At this operating point the engine returns 14 % for installation handling allowance.
  • At this operating point the engine returns 4.5 motors / min for motor installation rate.

How this compares with the baseline

  • Against the tool's baseline example, where installation handling allowance sits at 12% and the headline result is 597 hr, this scenario comes in 1.79% above the baseline at 608 hr.
  • It divides units by the install rate to get base labor time, then inflates it by the handling allowance to give required installation labor in hours. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required motor installation labor: 608 hr (headline result)
  • Base motor installation time: 533 hr
  • Installation handling allowance: 14 %
  • Motor installation rate: 4.5 motors / min
