151Z3015 Danfoss TMT 630 Wheel Motor 629cc High Torque Orbit
The Danfoss TMT 630 orbital motor is the largest frame in the TMT series, designed for heavy-duty applications requiring high torque and controlled low-speed operation.
With 629.1 cm³ displacement, it delivers 1,830 Nm continuous torque, up to 2,740 Nm peak torque, and supports 125 L/min continuous flow. Its pressure rating reaches 200 bar continuous and 300 bar peak, making it suitable for demanding mobile machinery.
Available in standard and wheel-motor configurations, it supports multiple shaft, flange, and port options. Standard code 151Z3015 and splined version 151Z3025 are available, with TMTW, TMT FL, and TMTU variants offered for specific machine requirements.

Description
Technical Parameters
Largest frame in the TMT range
629.1
cm³ swept every revolution
1,830 N·m held continuously, 2,740 N·m at peak, and a shaft that tops out at 200 rpm. Codes 151Z3015 and 151Z3025.
Most of these motors drive a wheel
On this frame the bearing arrangement is designed for heavy radial load, so the wheel-motor body is the usual specification rather than the exception. The TMTW version carries a recessed wheel flange with a 180 mm spigot on a 210 mm bolt circle, which puts the wheel straight onto the motor and removes the need for a separate hub or a cardan shaft.
06 Oil flow 125 L/min continuous and 150 L/min intermittent, unchanged across the range.
07 Output 27 kW continuous and 33 kW intermittent, which is 36 hp and 44 hp.
08 Starting torque 1,600 N·m at the continuous drop, 1,980 N·m intermittently.
09 Inlet ceiling 270 / 370 / 420 bar; return with drain line 140 / 175 / 210 bar.
10 Breakaway on 6 bar with the shaft unloaded.
When this frame is the wrong answer
Above the 630 there is nowhere to go in the orbit-motor family, and the frame itself gives away speed and pressure to reach its torque: 200 rpm and 300 bar at peak, against 270 rpm and 400 bar on the 470. A machine that needs to travel quickly, or that makes short overloaded pushes, will be better served by a smaller displacement working at higher pressure.
Where the 630 earns its place is on slow, heavy functions - harvester heads, beet harvester row units, trencher and compactor drives - and on wheel applications where the machine must climb or pull rather than hurry. When more torque is still required, the practical route is a change of gearing or of system pressure rather than a larger motor, because nothing above this frame exists in the series.
Before you specify the 630
Which code do I order for a standard machine?
151Z3015 covers the plain 40 mm shaft on the 160 mm spigot with G 3/4 ports, and 151Z3025 the 1-1/2 in splined shaft. Wheel bodies carry their own code, so tell us if the motor drives a wheel directly rather than through a coupling.
Can the body be built without bearings or with a brake?
Both exist on this displacement. The bearingless TMTU body is intended for building into a gearbox or hub, and the TMT FL body has a holding brake inside it for parking and for retaining a load on a slope.
