DIRECT DRIVE SEALED MOTORS

Kaybee heat resistant sealed motors were developed as a direct drive unit to withstand shaft temperatures up to 2100° F under pressure, vacuum and high ambient temperature conditions. The unit is ideally suited for metallurgical applications such as carburizing, nitriding, cyaniding, clean annealing and vacuum heat treating, which require both high temperature and gas tight sealing.

The unique liquid-cooled design of the Kaybee motor winding and shaft prevents heat conduction to the bearings and allows for continuous operation in high ambient temperatures. It also allows for hermetic sealing to be achieved without the use of expensive, high maintenance mechanical seals because the motor does not require a through-shaft for the cooling fan. Mating flanges are sealed with o-rings and the bearings are regreasable. Lubrication and proper water flow is the only maintenance required for the life of the motor.
