Connecting the rotor to the drive shaft
You can connect the rotor of the 1FW3 motor to the customer drive shaft either using a
flange or a clamping element:
Shaft height
Threaded hole at the rotor DE (face side)
Tensioning elements in the inner
diameter of the rotor

Preconditions for smooth, vibration-free operation
Preconditions for smooth, vibration-free operation include:
● A stable foundation design
● Precise motor alignment.
Comply with the following mounting instructions:
● Ensure a stiff mounting design, especially when flange mounting high-speed motors. As a
consequence, you shift the natural mounting frequency above the maximum rotational
frequency.
● Align the motors using shims under the mounting feet. This avoids deforming/distorting
the motor. Use the fewest possible shims.
● To securely fix the motor and transfer the drive torque, use bolts with property class 8.8.
