ABB Motors M2QA
Bearing seals
M2CA motors have, as standard, V-rings at both ends. The size and type of suitable seals are in accordance with the table below
Bearing life
The calculated bearing life L10 for power transmission by means of a coupling (horizontal machine): Motor sizes M2QA 280 to 400 > 200,000 hours
Pulley diameter
When the desired bearing life has been determined, the minimum permissible pulley diameter can be calculated using FR, as follows
Permissible loading
Motors are B3 version with force directed sideways. In some cases the strength of the shaft affects the permissible forces.
Rating plate
The rating plate is in table form giving values for speed, current and power factor for three voltages.
