BM7 OMT250 Hydraulic Motor - Built for Motion, Designed for Travel Drives
The BM7 OMT250 hydraulic motor is the one that moves the machine.
Other motors in the family turn conveyors, spin winches, or shake compactors. This one propels wheels and tracks. Loaders, excavators, telehandlers, skid steers - if it moves itself, this is the motor that does it.
"BMT" stands for "Built for Motion." Not a tagline - a design brief. The motor is built for the specific demands of hydrostatic travel drives: high starting torque, smooth low-speed control, compact packaging, and continuous operation.
If your equipment needs to move - not just power an attachment - the OMT/BMT is the one you spec.
What makes travel drives different
A travel drive is not like running a conveyor. Here's what changes:
Starting under load. The machine sits on the motor. When you start moving, the motor must deliver full torque from a standstill. No running start, no momentum to help - just raw torque to overcome inertia.
Low-speed precision. Maneuvering in tight spaces means creeping along at barely visible speeds. The motor must run smoothly at very low RPM - no jerking, no stalling.
Tight spaces. Wheel hubs and track frames don't have extra room. The motor has to fit in a compact envelope.
Continuous operation. Travel drives run for hours. The motor has to handle continuous load without overheating or wearing out.
Got to know this motor
When you're looking at a travel drive motor, you're really asking a handful of practical questions. Here's how the BM7 OMT250 hydraulic motor answers each one.
1. What makes it different from other motors?
It's designed for travel drives. Other motors turn things. This one moves machines. The difference is in the torque curve, the low-speed stability, and the mounting configuration.
2. What about starting torque?
High. That's the point. The motor delivers enough torque to start moving from a standstill under full load. No stalling, no hesitation.
3. How smooth is it at low speed?
Smooth. Very smooth. The motor runs steadily at low RPM - important for precision maneuvering. You can inch the machine forward without jerking.
4. How do I control it?
The motor has pre-installed interfaces for sensors and control valves. You can close-loop control speed, position, or torque electronically. No complex external piping.
5. How do I install it?
Mounts directly in the wheel hub or track frame. Confirm flange and shaft configuration matches your machine. The motor is compact enough to fit in tight spaces.
6. What about maintenance?
Monitor oil cleanliness and temperature. Check connections regularly. Travel drives run hard - keep the oil clean and the motor lasts.
Product detail
Our service
We have a team of skilled engineers ready to support you in your product development journey from test sample to production.
More than 30 years hydraulic valve production experience
A professional hydraulic valve production management team of more than 200 people
Annual supply of more than 10,000 container of specialized products
At least 10 inspection procedures are carried out before each batch is shipped

Installation notes
Mounting: Directly in the wheel hub or track drive. Make sure the flange and shaft configuration fits your machine.
Control interfaces: Already built in for sensors and valves. Wire them up to match your electronic control system.
Case drain: Check the back-pressure spec. In closed-loop systems, make sure the charge pump delivers enough flow to keep the motor cool and lubricated.
Start-up: Go through all connections before you fire it up. Verify the control signal and sensor readings before running at full load.
Oil: Use the recommended hydraulic oil - right viscosity, clean. Travel drives work hard, so keep an eye on oil temperature.
Where it belongs
If your equipment needs to move itself, the BM7 OMT250 is the one you spec:
Wheel loaders - front and rear axle drive
Compact excavators - track drive
Telehandlers - wheel drive
Skid steer loaders - independent wheel control
Agricultural equipment - self-propelled sprayers, harvesters
Special vehicles - custom mobile equipment

FAQ
Q: What are the available mounting configurations and shaft extension options for OMT BMT motors?
A: A variety of standard configurations are available, including flange mounting, shaft extensions, and port options. Specific selections are determined based on installation space and load requirements. Port interfaces can also be customized to suit the vehicle's overall layout.
Q: Why are OMT BMT motors suitable for travel drives?
A: There are four reasons: the radial piston design delivers high torque output; they offer good low-speed stability; they feature a compact design; and they include integrated control interfaces.
Q: Can OMT and BMT motors be used in closed-loop circuits?
A: Yes. OMT and BMT motors are designed for propel drives, and closed-loop circuits are a common application. However, it is necessary to verify that the case drain port configuration meets the back-pressure requirements of the closed-loop system and that the charge pump flow rate is sufficient to meet the motor's cooling and lubrication needs.
Q: Do OMT BMT units require regular maintenance?
A: Regular inspections are required for: fluid cleanliness and temperature; the condition of pipeline connections; the presence of any shaft seal leakage; whether operating noise and vibration levels are normal; and the reliability of sensor and control valve connections.
Q: How is the low-speed stability of OMT BMT motors?
A: They offer excellent low-speed stability, capable of operating smoothly at extremely low speeds. They are well-suited for propel drive applications requiring slow starts, precise positioning, or smooth control.
Q: What causes insufficient output torque or weak travel performance in OMT BMT motors?
A: Check the system pressure and flow rate. If these are normal, the issue may be increased internal leakage caused by internal motor wear. Check the cleanliness of the hydraulic fluid; if contamination is present, flush the system and replace the fluid and filter element. Another possibility is that the control signal is not being output correctly.
