When a customer requests a motor be rewound for a new set of conditions, that is typically what we in the service center industry provide them. However, there are occasions where the customer request may be fulfilled by reconnection; in some cases, this is done simply by revising the motor nameplate data. The purpose of this article is to identify and explain some of these scenarios.

Reconnections covered include:

  • Part winding start (PWS)
  • Single voltage 12 leads
  • 2 wye and 1 delta
  • 230/460-575 volts 380 volts 50 Hz and 460 volts 60 Hz
  • 2300 and 4000 volts

For an additional reference, see "Variables to consider when making motor frequency changes between 50, 60 Hz" published November 2008.
