LACONIA, NH / ACCESS Newsline / October 29, 2025 / ePropelled, a worldwide chief in clever engine and propulsion programs, right now introduced the enlargement of its GPM Collection, a household of built-in propulsion programs purpose-built for unmanned floor automobiles (UGVs) and autonomous mobility platforms.

The vary now contains the GPM35, GPM50 and the flagship GPM70, which mix high-efficiency motors, clever controllers and optionally available built-in planetary gearboxes to ship distinctive torque, efficiency and reliability in compact, rugged packages.

Preferrred for purposes equivalent to battlefield robotics, perimeter safety, logistics help and different demanding, rigorously examined autonomous deployments, the GPM Collection permits next-generation mobility in contested and sophisticated environments.

The GPM collection works seamlessly with ePropelled’s UGV energy technology, vitality conversion administration and hybrid-ready propulsion options, offering the muse for sustainable, and mission-adaptable, extended-range unmanned programs.

In accordance with researchers International Defense, Security and Technology, Inc. The worldwide navy UGV market (2025) is estimated at $1.89 billion, and is anticipated to achieve $2.91 billion by 2030 at a CAGR of 9.07%.

Scalable energy for any UGV class

The GPM Collection presents a variety of energy and torque outputs to fulfill the various calls for of small, medium and heavy floor platforms. All GPM drives function built-in high-resolution encoder suggestions for exact velocity and place management, making certain constant traction, exact torque response and superior stability underneath variable terrain circumstances.

• GPM35 – Compact energy for autonomous mobility
  With a steady energy of 4 kW / 8 kW peak energy and a torque of 35 Nm, the GPM35 is good for compact and lightweight UGVs. Together with ePropelled’s built-in 4:1 planetary gearbox, torque will increase to 140 Nm, offering robust pulling energy at low speeds and improved management on tough terrain. With an effectivity of over 90%, IP67 safety and an working vary of −40°C to +60°C, the 13.5 kg GPM35 combines sturdiness with simplicity of integration.

• GPM50 – Rugged drive for demanding missions
  Designed for increased load tactical purposes, the GPM50 delivers 6 kW steady energy / 11 kW peak energy and 52 Nm of torque, with superior field-oriented management (FOC) making certain exact torque supply and stability.
  The built-in planetary gearbox permits customizable torque multiplication, offering adaptability for all sorts of missions and masses.

• GPM70 – Excessive torque energy for heavy obligation platforms
  The GPM70, an built-in everlasting magnet synchronous motor (PMSM) with built-in controller, is designed for heavy-duty UGVs and autonomous industrial programs. With a base torque of 70 Nm, the optionally available 8:1 built-in gearbox will increase torque to 560 Nm, delivering distinctive pulling energy and traction for demanding floor purposes. The system presents easy operation, excessive vitality effectivity and is IP67 rated for defense in opposition to mud and water strain. It operates successfully from −40°C to +80°C and ensures reliability underneath excessive environmental circumstances.

Versatile energy integration

All GPM programs are appropriate with battery packs starting from 16S (48V) to 24S (96V), permitting versatile integration between electrical and hybrid UGV platforms. This broad voltage vary gives OEMs and system integrators with design flexibility for a number of mission profiles, from quiet electrical operation to hybrid endurance configurations.

Built-in planetary gearboxes for improved torque and management

Every GPM mannequin might be outfitted with built-in planetary gearboxes designed to ship optimum torque multiplication, effectivity and responsiveness. Out there in 4:1 and eight:1 ratios, these gearboxes rework the engines’ unique torque for elevated pulling energy and superior management on difficult terrain. Designed with precision gearing and sturdy supplies, these built-in programs keep compact kind elements whereas minimizing energy loss and noise, making certain easy, environment friendly operation in a variety of UGV purposes, from mild reconnaissance automobiles to heavy autonomous platforms.

Smarter by design

Every member of the GPM collection options ePConnected™, ePropelled’s clever information and management platform that gives:

• Actual-time monitoring of efficiency and temperature

• Predictive diagnostics and analytics for proactive upkeep

• Over-the-air (OTA) software program updates and parameter adjustment

• Help for driver enter together with joystick instructions, braking, directional management and eco/efficiency modes

Every ePropelled GPM drive options encoder-based closed-loop velocity and place management as customary, enabling exact velocity management, improved low-speed stability and synchronization in multi-motor UGV configurations – important for autonomous navigation and coordinated powertrain efficiency. Encoder information might be seamlessly built-in with the ePConnect™ analytics layer to help predictive upkeep and adaptive management optimization. Redundant encoder channels are carried out in all GPM drives to make sure steady suggestions and dependable operation in safety-critical and dual-drive UGV platforms. This mix of intelligence and strong know-how ensures most uptime, mission adaptability and vitality effectivity within the discipline.

Designed for any atmosphere

The GPM Collection is a part of ePropelled’s broader UGV ecosystem, which incorporates energy technology and conversion administration options designed to resist harsh floor circumstances, tough terrain and steady autonomous operation.

By unifying propulsion, management and information intelligence, ePropelled permits UGVs to attain longer vary, improved maneuverability and full autonomy, supporting superior protection, industrial and analysis missions worldwide.

“The GPM Collection represents the following technology of clever, built-in propulsion for unmanned programs,” mentioned Chris Thompson, VP International Gross sales. “With our GPM35, GPM50 and GPM70, we’re giving OEMs a whole, scalable propulsion platform that delivers energy, precision and connectivity, all in compact, rugged programs designed for mission success.”

“Digital Ideas Engineering has labored with ePropelled to optimize their GPM collection engines for floor traction purposes and has built-in a pair of GPM50 engines right into a high-performance European UGV mission that’s progressing efficiently by testing and trials. We look ahead to continued collaboration with ePropelled, combining their superior engine developments with our proprietary applied sciences to provide world-class autonomous UGVs” – Ed Gummow, Engineering Director, DCE.
