HMA2, HMC2, HMD, HMT, MS, Y2E1, Y2E2, YDT standard Hoyer IEC Squirrel-Cage Motors
These motors are manufactured in accordance with IEC/EN 60034-4 and IEC/EN 60072. Motors are rated for the ambient temperature range -20°C to +40°C and site altitudes ≤1000 m above sea level. Low-voltage motors are components for installation in machinery. They are CE marked according to the Low Voltage Directive 2006/95/EC.
Applicable standards and specifications
The motors comply with the appropriate standards and regulations,especially those listed in the table below.
The motors comply with the IEC or European standards listed above. The European standards replace the national standards in the following European countries: Germany (VDE), France (NF C), Belgium (NBNC), Great Britain (BS), Italy (CEI), Netherlands (NEN), Sweden (SS), Switzerland (SEV) etc.
The motors also comply with various national standards.
The following standards (with the exception of non-standard motors) have been harmonized with IEC publication 60034-1 or replaced with DIN EN 60034-1 so that the motors can be operated at standard rated output.
