Ordering the Correct 1PH8 Configuration
The 1PH8107-1DF12 base code defines the motor’s size, electrical rating and cooling. The suffix -1GA1 defines the mechanical and encoder configuration. When replacing an existing motor, quote the full order number and serial number from the rating plate so the identical version is supplied.
