New and Original Yaskawa AC Servo Motor 1500RMP SGMG-30ASASAR New in Box

General Electric high thrust vertical motors covered by these instructions are carefully constructed of high quality materials and are designed to give long and trouble-free service when properly installed and maintained. These motors are generally used to drive pumps.

Both HOLLOW-SHAFT and SOLID-SHAFT motors are described in this instruction book. Hollow-shaft construction is available in frame sizes 213 and larger whereas solid-shaft construction is available in 182 and larger. Figures 4-6 show typical hollow-shaft high thrust motors and Figures 7-9 show typical solid-shaft high thrust construction. Solid-shaft high thrust motors are not suitable for driving loads that impose significant radial load on the motor shaft; they should not, for example, be used for belt drive applications.

Spherical roller bearings are sometimes used for applications requiring extra high down-thrust capacity and/or extra bearing life; these bearings may require water cooling. See Figure 10. Motors with spherical roller thrust bearings also require a certain minimum down thrust during all continuous operations.

Since overloading greatly reduces bearing life, the amount of thrust applied should not exceed the recommended values. This instruction book applies to motors with Totally Enclosed Fan Cooled enclosures as defined by Yaskawa .
