<p>The front endcap (10) and mounting bracket (26) for a motor are unitary for motor interchangeability. The endcap (10) has a disc-like portion (12) and a tubular boss (22) extending therefrom that receives in its bore the motor shaft (44) and bearings (68). A portion (50) of the motor shaft extends beyond the boss to receive a sheave (56), a rim portion (72) of which extends over the boss so that the sheave load is more in line with the bearings. Furthermore, the sheave may be bolted to the endcap boss for motor replacement.</p> |
