Farmers and food processors rely on electric motors for a range of purposes, but they cost a lot to run. In fact, the energy to run an electric motor for several weeks can cost more than the motor itself, so it really pays to look at your options.
High-efficiency motors and variable speed drives may both save considerable energy and have relatively short payback periods.
High-efficiency motors are designed to keep energy losses to a minimum. Variable speed drive equipment controls motor speed to match load and save energy. They are particularly useful for pumps, cooling, and ventilation where output needs vary. Combining high-efficiency motors and variable speed drives, and implementing a motor management system are smart strategies.
