How is the ‘New’ Motor Better Than the ‘Old’ Motor?
1) Higher Ambient Temp Rating: The ‘New’ motor has a 50-degree-celcius ambient
temp rating, as opposed to the 40-degree-celcius rating of the ‘Old’ motor.
2) Improved Bearing Configuration: The ‘New’ motor has shaft bearings which are
pressed more tightly into end frame castings; where the bearings are constrained around
their outside diameter by a bushing and a ring of steel which is insert-cast into the
aluminum end frame. This improved bearing configuration reduces instances of the
vibration/failure in which the bearing O.D. vibrates against the I.D. of the end frame
casting.
3) Ease-of-Wiring: The ‘New’ motor has an easier-to-wire terminal block compared to the
‘Old’ motor. The ‘Old’ motor has a small half-moon shaped wiring compartment cover; it
can be challenging to pull the electrical wires through the conduit port and fix them into
place at the electrical terminal screws. The ‘New’ motor has a large plastic shell which
encapsulates the terminal block area. The plastic shell removes with one screw, revealing
the terminal block area, allowing clear and easy access from a wider range of angles.
