Motors should be kept clean to help them cool properly. For Induction motors an Electronic soft starter, which are ready available in markets, boosts the efficiency of motors, operating below their rated output. Energy savings for significant for motors operating at less than 50% load for 50% of time.
Use shunt capacitors across motor terminals to reduce KVA charges and also avoid damage to motors.
Keep the main switch of installation as near the motor as possible, so that we can switch off the supply immediately after use.
Lubricate motors and motor drives regularly to reduce friction.
Tighten belts and pulley at regular intervals to reduce loss of energy due to 'slip'.
Motor should be placed as close to the load as possible.
The windings of any under loaded, 3 phase motors can be re-connected in star rather than Delta connection. This reduces the voltages across the windings to give 58% of the rated values. Hence motors running at less than 58% of full load will be benefited. This is a cheaper option buying a smallar motor and as per studies conducted, the difference in performance between star connected and standard and these motors is minimal.
Make greater use of daylight.
Match motors to your requirement. Oversized motors will waste energy. Use motors of high efficiency.
Replace worn out bearings immediately and ensure timely repairs.
Use ISI - Brand motors
Every time the motor is rewound, its efficiency comes down by 2 to 10% even if wire of adequate size is used. On an average a new motor burnt out and rewound losses about 5% efficiency due to heat damange to steel laminations.
