Lin Engineering introduce new commerical grade Vacuum Motor
2005.03.01 - Lin Engineering, the step motor specialists, is pleased to announce the release of their 1.8 degree, Nema 11 Vacuum Motors. The 211 vacuum rated series motors are capable of up to16 oz-in of holding torque depending on stack size and are ideal for commercial grade vacuums of 10-4 Torr to 10-7 Torr.
The Nema size 11, 1.8 degree motor measures a mere 1.1” square and is available in three lengths; the 211-13 is 1.24”, the 211-18 is 1.75” and the 211-20 is 1.99”. It provides high torque in a small package. The 211-13 produces 9.2 oz-in of holding torque; the 211-18 produces 13.7 oz-in of holding torque; and the 211-20 produces 16.6 oz-in of holding torque.
In order to make these small but powerful motors vacuum rated Lin Engineering insures that all of the special handling and parts necessary are used in the manufacturing process. First of all, all paint and oils are removed from the motor. Next, high temperature windings are utilized as well as Teflon leads. Lastly, depending on the rating of the vacuum environment, either no-lube stainless steel bearings or special-lube stainless steel bearings are use. During all of the manufacturing process latex gloves are worn to insure that no residue from human touch is left behind on the motors. All of the above special parts and handling insure that limited outgassing and contamination will occur.
