TMS03 Modular Radial Piston Motor
The smallest frame in THOTH’s modular TMS family — sphere-piston radial motor with disc distribution, available in both shaft-type and wheel-type configurations.
TMS is a low-speed, high-torque radial piston motor with an advanced disc-distribution flow design and sphere-piston structure. It runs smoothly at speeds as low as 2 r/min without torque ripple — the behaviour that matters in precision slewing, traction, and positioning drives.
The TMS03 frame covers 160 – 400 ml/r and comes in both shaft-type and wheel-type configurations — the shaft type for direct-coupled drives, the wheel type mounting inside the wheel hub to eliminate the axle shaft and gearbox. The modular design means the motor core, brake module, and valve options are independently configurable.
Widely applied in mining, cranes, geologic drilling, and construction machinery.
