TM-2 (J0) Series
TM-2 (J0) Torque Motor with Closed Cooling
- Type
- Torque motor with closed cooling jacket
- Frames
- 4 (Ø329 - Ø572 mm with jacket)
- Continuous Torque (WC)
- 228 - 3,825 N·m
- Peak Torque (1 s)
- 453 - 6,900 N·m
The TM-2 (J0) is the TM-2 torque motor with the water-cooling jacket added: a closed cooling sleeve with a water-tight seal, so there is no jacket to design or assemble on the machine side. The large hollow shaft still swallows cables and utilities, and cogging torque is reduced down to 50%.
The same frames without the jacket: TM-2 is the base frameless motor when the machine supplies the cooling circuit. View TM-2 Series →

Frames
Frame code = stator external diameter including the jacket, second character = rotor height (40 to 170 mm); each model in the frame tables winds two ways, and the torque columns span the windings. Continuous ratings assume water cooling through the integrated jacket.

Windings
Winding choice lives in the frame tables: each model prints two executions with their own torque, speed and current ratings.
- L / P / S Winding families — Two windings per model; ratings per the frame tables
Cooling jacket
The reserved code at the end of the model number carries the jacket execution.
- J0 Jacket without bridge — The standard closed-cooling execution
- J3 Jacket with bridge
Temperature sensors
- 0 PTC130 + PTC100 + Pt1000 — Standard in-winding set
- 1 PTC130 + PTC100 + Pt1000 x3 — Triple set
