ITEM

DESCRIPTION

32 TEMPERATURE DETECTORS A bimetallic temperature-sensing device is mounted on the commutating coil. The device is available with normally open or normally closed contactors. Specify whether normally open or normally closed contacts are required. (Included as standard on TEUC motors). Thermostats are typically normally closed and the opening temperature is between 120° C to 150°C. Thermostats with special temperature rating are non-standard. Refer to Wolong when required.

33 VERTICAL MOUNTING (FOOTED) The following applies to vertically-operated foot- or flange-mounted, standard ball bearing, motors where no external thrust is reflected back to the motor shaft. Refer to Wolong for external thrust limitations. For vertical brake applications, refer to Modification Item 8a. Note: For crane motors, refer to page 3.11, Item 13. All drip - proof and splash - proof motors which are mounted vertically require non-standard covers (the louvers are rotated to provide protection in the vertical position). Totally enclosed motors require no modifications to the covers. Frames CD180AT-CD320AT do not require internal modification for vertical mounting. Thus, a standard motor in these frame sizes is suitable for vertical mounting. Frames CD360AT-CD6900 require internal modification for vertical mounting. Thus, a standard motor in these frame sizes is not suitable for vertical mounting. The CD365AT-CD5010AY frames require shaft seals for vertical mounting with the shaft down. The CD365AT-CD5010AY frames mounted shaft up require additional modifications to the bearings and shaft. Refer to Wolong for applications involving vertical mounting of CD6000-CD6900 frames.
