I'm thinking about replacing the motor on a used surface grinder and seeking brand recommendations.
The grinder currently has a GE K163 (1 HP, 3450 rpm, TENV, 3-phase) driven by an Hitachi L100 VFD. It's belt driven.
The bearings on the motor are probably bad  so my options are to replace the bearings or the motor. Is the GE worth repairing or should it be replaced with a Baldor, Leeson or something else?
 With the belts off, the motor makes some noise on startup and a cup of water sitting on the spindle housing has standing waves on the surface. Thanks to Forrest for that cup of water tip.
