8.3 Cooler connection
In the case a built-in torque motor with a cooling jacket, the coolant must be
supplied/discharged via two holes (cut by the user) in the axes construction (see following
diagrams). For information on the installation hole fit, refer to the section titled "Installation
drawings/Dimension drawings".
To ensure optimized, uniform cooling across all cooling slots, the coolant infeed for torque
To ensure optimized, uniform cooling across all cooling slots, the coolant infeed for torque
motors 1FW609 and 1FW613 must be offset by 90° vis-à-vis the cable outlet for the
electrical supply. If a different location is selected for the coolant inlet/outlet, the coolant is
not distributed evenly in the cooling slots. The least favorable position for the coolant
inlet/outlet is at an angle of 90° counter-clockwise because, in this case, the coolant can
barely flow through the foremost or rearmost cooling slots.
The coolant infeed must be positioned directly above the exit point of the electrical cable
The coolant infeed must be positioned directly above the exit point of the electrical cable
outlets on 1FW615 torque motors.
