Mistervalve GPT IE3 Technical Information

Totally enclosed squirrel cage, TEFC, three phase motors type HMA3 (aluminum) in size 56 to 132 (size 160 and 180 on request) and type HMC3 (cast iron) in size 160 to 400 (below size 160 and bigger than size 400 on request).

Rotor is casted with 100% pure aluminum and shaft is made of high quality C45 steel. 

Stator winding is made with double coated copper wire and phase to phase insulation. The insulation system is Class F, maximum 105K temperature rise at 40°C ambient tem-perature. Motors below 200kW are designed for Class B temperature rise. Class H insulation system can be delivered on request.

All motors are manufactured according to IEC 60034, IEC60072, EN50347 and tested according to IEC60034-2-1.Rotor is dynamically balanced with half key to fullfill vibra-tion level IEC60034-14 grade A.

Sound level within limits of IEC60034-9.Standard voltages:400V Y – Hoyer IE3 Motors ≤ 3kW400V D – Hoyer IE3 Motors > 3kWOther voltages can be supplied on request.

Mistervalve GPT IE3 motors are with PTC terminal protection. Mo-tors can be modified with bimetal detector, heating ele-ments for stand still protection and PT100 for both winding and bearings on request.

Mistervalve GPT IE3 Motors are as standard IP55, prepared for drain holes. Higher protection class on request. All motors are delivered with blind caps in the terminal box.

Mistervalve GPT IE3 motors are painted black RAL 9005 with low gloss for use in normal industrial environments.
