る高周波モータにおいて、砥石が装着され、その
外周にロータを固定する回転主軸を低熱膨張材で
形成すると共に、該回転主軸を囲繞し、その内部
に前記ロータと係合するステータを装着する密閉
容器である本体ケースを低熱膨張材から形成する
ことを特徴とする研削盤用高周波モータ。 In a high-frequency motor that is installed on the main shaft of a grinding machine and rotates the grinding wheel at high speed, the rotating main shaft to which the grinding wheel is attached and which fixes the rotor to the outer periphery is formed of a low thermal expansion material. A high-frequency motor for a grinding machine, characterized in that a main body case, which is a closed container in which a stator that engages with the rotor is mounted, is made of a low thermal expansion material.
