Note 1: GYS motors with keys are not tapped for voltages of 0.1kW or less and are tapped for voltagesof 0.2kW or more.

Note 2: Types with oil seals are made-to-order, so some specifications may differ from those of standard stock products.

Note 3: Select unmarked or B type for GYB lead wire types.
