Electric motors and variable speed drives are used throughout the pharmaceutical manufacturing industry to operate HVAC systems, laboratory or bulk manufacturing equipment, such as mixers, pumps, centrifuges and dryers, and to move and operate filling and finishing equipment.
Maintenance can save from 2% to 30% of total motor system energy use in pharmaceutical production. Electric motors and variable speed drives are often sized incorrectly in the pharmaceutical manufacturing industry.Ensuring that motors are properly sized, and that oversized motors are replaced, can save 1.2% of total electric motor electricity consumption within one system. Typically whenever peak loads can be reduced, so can motor size.
Replacing an old electric motor with a high-efficiency motor is usually a better choice than rewinding a motor. Currently, there are no quality or efficiency standards for rewinding, this can create motor efficiency to decrease from 2% to 25% after rewinding. If you are thinking aboutwhether to rewind a motor or to replace it with a higher-efficiency model, consider the following prior to making a decision:
- Never rewind a motor damaged by excessive heat
- Replace motors that are less than 100 hp and more than 15 years old
- Replace any motors that have previously been rewound
High-efficiency motors, meeting or exceeding performance criteria published by the National Electrical Manufacturers Association (NEMA), reduce energy losses through improved design, better materials, tighter tolerances and improved manufacturing techniques.
