What it is

A lean version of a motor shop: you diagnose and fix smaller motors (pumps, fans, blowers, compressors, workshop machines) with bearings, capacitors, seals and cleaning, and pass complex rewinds to a partner shop.

Your first three steps

  1. Get hands-on training in motor testing and bearing work, and line up a rewind shop that will take your larger jobs
  2. Set up a bench with a megohmmeter, multimeter, bearing puller and press, and a safe lifting setup
  3. Contact local HVAC contractors, farms and workshops offering fast turnaround on small motor repairs
Who pays

Farms, small manufacturers, HVAC and pool contractors, repair businesses, woodworking and machine shops, and property maintenance teams.

How it makes money

Flat or hourly bench fees per repair, parts markup, and a referral margin or trade price on work you subcontract to a larger rewind shop.
