Motor Installation
2.5.1 Motor Mounting
To provide good mechanical alignment, the mounting surface of the motor face plate is
held perpendicular to the motor shaft to within 0.005 inches. Projecting above the plane
of the mounting surface is a close tolerance circular pilot boss. Matching the pilot boss
with a pilot hole in the mounting structure facilitates interchanging the motor and
minimizes the need for mechanical adjustments. The mounting surface is fitted with
four holes equally spaced on a bolt circle pattern.
The mounting panel must be stiff enough so it does not deflect significantly when radial
loads are applied to the motor shaft. The mounting panel should also have good
thermal conductivity especially if peak performance is demanded of the motor.
Mechanical shock to the motor case or shaft (e.g., from striking or dropping)
must be avoided to prevent damage to the motor. Possible results from
striking or dropping include: Misalignment of the resolver; damage to
armature bearings; cracking of the motor case; unbonding or demagnetization
of the permanent magnets. Any of these would render the motor
unserviceable.
2.5.2 Conduit Installation
The following procedure must be followed to assure a waterproof motor installation will
be water-tight.
Remove the rear cover from the motor and install the supplied "O" ring into the
Ø
groove of the cover.
Wrap the threads of the NPT conduit fitting with at least 2 layers of Teflon
Ø
Install the fitting into the motor threads and tighten at least 1 turn after hand
Ø
tightening. Do not over torque.
Make the motor wire connections as necessary. DO NOT TIN THE WIRES. Tinning
Ø
will compromise the long term integrity of the connection.
Apply a high temperature (100° C.; 212° F.) rated grease (Lubriko ACZ or
Ø
equivalent) to the "O" ring.
Install the rear motor cover by tapping it into place taking care not to damage the "O"
Ø
ring.
Secure the cover with the four screws provided.

2.5.3 Load Coupling
A flexible coupling MUST be used between the motor shaft and the load to minimize
mechanical stress due to radial loads, axial loads and/or misalignment. Radial and axial
loading cannot exceed specified values. See Table 2-1.
