3.4. Mounting the Motor
DANGER
HOT SURFACES
The motor's surface can heat up to more than 70°C in certain types of
use.
• Avoid contact with hot surfaces.
• Do not place flammable or heat-sensitive components in the
immediate vicinity.
• Assemble components in the best way for heat dissipation.
• Check the temperature when performing a test.
Failure to comply with these precautions can result in injury or
damage to equipment.
WARNING
UNEXPECTED MOVEMENT DUE TO ELECTROSTATIC DISCHARGES
Electrostatic discharges (ESD) on the shaft can, in rare cases, lead to
encoder system failures and generate unexpected motor movements.
• Use conductive parts (e.g. antistatic straps) or other appropriate
measures to avoid a static charge due to movement.
Failure to comply with these precautions can result in death,
serious injury or damage to equipment.
WARNING
UNINTENDED BEHAVIOR CAUSED BY MECHANICAL DAMAGE TO THE
MOTOR
Exceeding the maximum permissible forces leads to rapid bearing
wear, a broken shaft or damage to the internal encoder.
• Never exceed the maximum axial and radial forces.
• Protect the shaft from any impact.
• When press-fitting components, do not exceed the maximum
permissible axial force.
Failure to comply with these precautions can result in death,
serious injury or damage to equipment.
Mounting position
The motor can be mounted in any position.
Mounting
When mounting the motor on the flange, the motor must be aligned precisely in both the axial and radial
directions. All the fixing screws must be tightened to the tightening torque stipulated by the application,
taking care not to generate any warping.
Install the transmission devices
If the transmission device is installed incorrectly, this can damage the motor.
Transmission devices such as pulleys and gears must be mounted in compliance with the maximum axial
and radial loads defined in each motor's technical data sheet.
Follow the transmission device manufacturer's assembly instructions.
The motor and the transmission device must be aligned precisely both axially and radially. If this is not done,
it will result in abnormal operation, damage to the bearings and significant wear.
