New and Original Yaskawa 1500r/min AC Servo Motor 2900W 23.8A SGMG-30ASAAB

Safe maintenance practices by qualified personnel are imperative. Before starting maintenance procedures, be positive that:

• Equipment connected to the shaft will not cause mechanical rotation.

• Main machine windings and all accessory devices associated with the work area are disconnected from electrical power sources.

If a high-potential insulation test is required, procedure and precautions outlined in NEMA Standards MG-1 and MG-2 should be followed.

Failure to properly ground the frame of this machine can cause serious injury to personnel. Grounding should be in accordance with the National Electrical Code and consistent with sound local practice.

It shows a typical solid shaft high thrust construction (on right side) for applications requiring continuous up and down thrust capability. In this type of motor, three angular contact ball bearings are mounted in opposed mounting with one bearing oriented to carry up thrust and two oriented to carry down thrust. If greater down-thrust capacity is required, motors may use two standard angular contact ball bearings and one split-race bearing which gives the capacity of 3 bearings down and one bearing up. This does, however, give more endplay than normal.
