Three-phase synchronous motors DS 45-100..540V

Radial force diagrams

Permissible radial forces F_R at the shaft end

All bearings manufacturer are dimensioned for a service life of approx. 20.000 operating hours; the loads specified in the following must not be exceeded. The specified permissible radial forces F_R are valid only for horizontal mounting of the motor without additional axial forces.

Axial load of the motor shaft

When mounting industrial clutches. industrial pulleys. etc. onto the motor shaft. axial forces must not occur! Therefore use the internal thread of the shaft end as assembly aid.

Example

Force acting on the end of the shaft end (for force acting on the middle of the shaft end Fr x 1.1) Bearing life 20.000 h; shaft end with keyway

Explanation of the example

The radial force Fr of the application is used to determine the possible maximum speed of the bearing in the "Ball bearing" characteristic.

Radial force 850 N => maximum speed 4250 min^-1The maximum transmittable torque results from the "Shaft" characteristic.

Radial force 850 N => maximum transmittable torque 185 Nm
