Motors


  • Properly maintain motors to maximize efficiency ensure reliability and reduce downtime and repair costs.
  • Make sure your motors are sized correctly and consider incorporating variable speed motors to reduce its energy usage.
  • Consider installing a buck-boost transformer as required to maximize the life expectancy of your motors. This is a worthwhile consideration for normal operating conditions, as well as during voltage reductions.
  • Tighten belts and pulleys at regular intervals to prevent slippage.
  • Lubricate motors and drives regularly to reduce friction.
  • Replace bearings when worn.
  • Replace worn or defective motors with motors sized as close to load as possible.
  • Keep motors clean to facilitate cooling.
  • Check the nameplate information on your motors and verify they are rated to operate at your supply voltage. Motors are normally designed to operate between plus-10 percent and minus-10 percent of their normal voltage without shortening life expectancy.
  • Check and adjust alignment between motor and drive equipment to reduce wear ad excessive torque.
  • Avoid aiming fans directly at motor starters. This practice may defeat controls designed to protect the motor from possible burnout.
