Made in the USA (PMI/Kollmorgen), heavy duty, direct replacement motor kit for the O.E.M. Yaskawa disc motor. Superior current handling capability. Fits all MTR-90 /100 / DTR- 900 & Mitsubishi Capstan motors.

Since our "NEW" motor kits are USA made, individual parts are not available, because these are not interchangeable with the OEM Japanese made parts.

Restored/reconditioned original equipment parts are tested good, with plenty of remaining life.

"Do-it-yourselfers" note that PMW is not responsible for motor failure due to improper field installation of parts. The servo-disc must be installed with proper clearance above the "flux return plate" and must be set with a "feeler gauge" or shim. The proper specs will be provided to you.
