Abstract

Un sistema incluye un compresor que incluye una carcasa que aloja un mecanismo de compresión impulsado por un motor eléctrico en un estado encendido y no impulsado por el motor eléctrico en un estado apagado. El sistema también incluye un convertidor de frecuencia variable que acciona el motor eléctrico en el estado encendido variando una frecuencia de un voltaje suministrado al motor eléctrico y suministra corriente eléctrica a un estator del motor eléctrico en el estado apagado para calentar el compresor.
