An AC drive or motor is a key component in virtually every facility that manufactures, fabricates, or constructs. Therefore, businesses can assume the worst for any logistics once they shut down without warning. Here are five crucial maintenance areas to help preserve business systems
Drive Input
Variable frequencies in an AC drive are integral in controlling its performance. However, a slight drive distortion can affect power grounding and motor performance. A 0.5Hz variation in drive input can drive communication problems, under power or wear out a motor.
Bus Testing
AC to DC bus conversions ensure excellent AC drive performance if it has adequate smoothing during conversion with the lowest ripple level possible. Any DC reading that goes above +/- 10% can cause major motor performance problems or indicate a malfunction in failing motors.
Drive Output
Any electric current and voltage deviation can result in a higher operating temperature. This situation can result in shortening the stator insulation lifespan. The drive output's voltage-to-frequency ratio can overheat the motor at high ratio levels. Plus, other ratio imbalances indicate DC bus and variable frequency switching issues.
Motor Input
Outside variable frequency generators, cable selection that serves as communication and control cables from drive to motors are always critical. Always check if your cables are within the motor's rating to avoid reflected voltage peaks that cause massive machine damage.
Motor Shaft Voltage
Lastly, the motor shaft voltage greatly matters because if voltages appear on the rotor shaft, the bearing grease's performance decreases. When this happens, it can pit and flute the motor causing permanent machine failure.
