Get a free ECM motor upgrade. Electrically commutated motors (ECMs) are typically installed on evaporator fans in grocery store coolers, freezers and cold storage areas. They are an energy efficient option to alternating current (AC) shaded-pole and permanent-split capacitor motors.

Keep your motors in the best working condition: Perform regular cleaning and maintenance on your motors. Tighten belts and pulleys to prevent slippage. Lubricate motors and drives regularly to reduce friction. Replace worn bearings.

Put your motors to sleep – Set continuous use motors, such as those found in elevators and escalators, to shut down or “sleep” after a certain period of inactivity or during hours when your building is unoccupied.

Voltage – Make sure the voltage applied to the motor is as close to the design limits as possible. (The limit can be found on the motor’s nameplate). Increasing the voltage at the motor outside of its design limits can lead to a decrease in the power factor and higher electrical costs.

Switch to efficient belts – Consider switching the V-belts to synchronous belts on motors in your facility. Synchronous belts offer increased reliability and are about 3% more efficient than V-belts. Due to their design, synchronous belts are less prone to slippage, improving their efficiency and do not require re-tensioning after installation.
