Description
Red-hot metal, cycles with overloads, dust and an aggressive environment require an especially strong design. The grey cast iron housing has annular ribs across the motor axis, which improves heat removal without a fan and reduces dirt build-up. Cooling is IC410, that is without its own ventilation. Speeds are 1500, 1000, 750, 600 and 500 rpm, lower on request. Protection degree is IP55, optionally IP56, IP65 and IP66, mounting IM B3, B35, B5, B14, B34 per EN 60034-7. Coolant temperature is −20…+40 °C, optionally −40…+60 °C, installation altitude up to 1000 m.
How to choose
From a frequency converter the operating speeds are matched precisely to the drive requirements, and since control lies mostly in the low-frequency range, it is advised to adapt the winding and use converters with automatic voltage boost or vector control. The windings are designed for such operation. There are catalogues of heavy-duty roller table motors for converters, geared motors and squirrel-cage motors for the grid and converters, and a brochure on class IE3 roller table motors. The series replaces ARM, 4AR and ARMZ on process and transport roller tables of steelmaking and rolling shops.

FAQ
What power and frames do ARC roller table motors have?
0.4–500 kW in frames 112–450, with direct roller drive or with a mounted gearbox.
Why does ARC have cooling without a fan?
The housing with annular ribs removes heat itself under scheme IC410 and collects less dirt. This is important for dust and red-hot metal.
What ambient temperature do the motors withstand?
As standard from −20 to +40 °C, optionally from −40 to +60 °C, at altitudes up to 1000 m.
Can ARC be fed from a frequency converter?
Yes, the windings are designed for such operation. For low frequencies, converters with automatic voltage boost or vector control are advised.
What speeds and protection degrees are available?
1500, 1000, 750, 600 and 500 rpm, lower on request. Protection IP55, optionally IP56, IP65 or IP66.
