3. PRECAUTIONS FOR USE CONCERNING THE MECHANICS
3.1. Data specific to the motor shaft
3.1.1. Press-fit force
WARNING
MOTOR MECHANISM
Exceeding the maximum permissible forces on the shaft leads to rapid
bearing wear, a broken shaft or damage to any accessories (encoder,
brake, etc.)
• 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.
The maximum press-fit force is limited by the maximum permissible axial force on the ball bearings.
This maximum axial force is stated in the motor technical data sheet.
Alternatively, the component to be fixed in position can be clamped, glued or shrunk-fit.
3.1.2. Radial load on the shaft
The application point
X
of the radial force
F
depends on the motor size.
This information appears in the motor technical data sheet.
The maximum axial and radial loads must not be applied simultaneously.
