Blower kits are used to cool motors that are running on low RPM’s (rotations per minute) and motors that are being used on variable frequency drives. Variable frequency drives are used in various appliances, drives and compressors. Protecting a motor from overheating is very important. Heat can destroy a motor, causing lost work time and high repair costs.
“These kits are used for converting LEESON motors to totally enclosed blower cooled motors. Cooling per MG1.6 (IC46). The kits are designed for inverter and vector drive applications where continuous cooling is required regardless of motor shaft speed. The kit is mounted on the back of the motor after removing the fan guard and fan. Modifying the shaft is not required.”-LEESON
