Description
Rolling mill type DC motors to AIST No. 1 (frame sizes 802–818 and 620–624) worked for decades in screwdowns, shears, roller tables and guide rulers, and thousands of such machines are still running. Their weak point is the commutator, which needs periodic turning, while an induction motor has no commutator. The design follows JEC-2137 / IEC 60034-1 while keeping mechanical and electrical compatibility with frame 800. The new-generation bearings are moisture-resistant, with a grease replenishment interval twice the usual. The motor is controlled by a frequency converter, for example the TMdrive-10e2. The manufacturer states higher efficiency, lower CO2 emissions, lower vibration and simpler maintenance.
How to choose
Two points decide. The first is the frame size of the DC motor being replaced, since compatibility is stated for frame 800. The second is the frequency converter, because an induction motor will not run without it. If a general industrial drive is needed with no tie to rolling mills, look at the 21-FII at 37–1400 kW in the TEFC version.

FAQ
Which motors does the TM-AC 800 Frame replace?
Rolling mill type auxiliary DC motors of frame 800 to AIST No. 1, working in screwdowns, shears, roller tables and guide rulers.
Is a frequency converter needed for this motor?
Yes, the motor runs from a frequency converter, for example the TMdrive-10e2.
What does giving up the commutator bring?
The component most prone to failure and the periodic turning of the commutator disappear. Maintenance becomes simpler.
To which standards is the motor designed?
To JEC-2137 / IEC 60034-1, with compatibility in dimensions and electrical parameters with frame 800 DC machines.
What is special about the bearings of this motor?
They are new-generation, moisture-resistant, for heavy conditions, and the grease is replenished half as often as in ordinary ones.
