Electric motor breakdown: What should I do?

An electric motor breakdown, whatever process is being run, is a major inconvenience and can lead to costly delays in production. You need to make a quick decision when an electric motor fails, so here are the key elements to consider:


When deciding whether to repair or replace a motor, first ask yourself whether it’s suitable for the application. Due to the long lifespan of high-quality motors, they may remain in place for many years while the connected equipment or process is changed over time. A like-for-like replacement or rewind will not be cost effective unless the motor is still appropriate for the job in hand.

Evidence of failure

Assess the motor and determine whether catastrophic failure has occurred. If this is the case, consider the cost of repair versus that of replacement. Catastrophic failure will cause considerable damage to key components such as the stator core and windings, so in the case of small to medium-sized motors a repair may not be economical.

Also check for evidence of historical catastrophic failure during your inspection – look for a bent shaft or damaged stator laminations, for example. Decide why failure has happened and take steps to prevent a recurrence.

Energy efficiency

Consider the return on investment should you buy a new energy-efficient motor; your supplier can help you calculate the payback period, which in many cases is less than 12 months.

However, you may have no choice. As energy-efficiency legislation becomes increasingly stringent, you must take your motor’s IE rating into account when choosing whether to repair or replace a motor. If the motor no longer meets the demands of EU MEPS then it will not be legal to replace it with one identically rated and an upgrade will be required.
