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.
The following information must be shown on the motor rating plate according to IEC 60038-30; 2008 and European MEPS (Commission Regulation, EC, No 640/2009)
– Lowest nominal efficiency at 100, 75 and 50 percent rated load – Efficiency level (IE2 or IE3) – Year of manufacture
