Electric Wheel Loader Powertrain Requirements
01
High Output Torque at Low Speeds
Loading and digging require high tractive force at low vehicle speeds. The electric powertrain must deliver high torque and maintain stable output under heavy loads and changing ground conditions.
02
Independent Traction & Hydraulic Power
Wheel loader working cycles involve rapidly changing traction and hydraulic power demands. Independent electric drives allow propulsion and hydraulic power to be controlled according to the requirements of each operation.
03
Responsive & Efficient Operation
Frequent acceleration, deceleration, and direction changes require responsive torque control and efficient power delivery. Motor and transmission control help maintain efficient operation across loading, transport, and return cycles.
Our Electric Wheel Loader Powertrain Solutions
We provide modular electric powertrain solutions for 5–7 ton wheel loaders. The solution combines a PMSM traction motor with a 2-speed AMT transmission for vehicle propulsion and an independent electric motor for hydraulic functions. This configuration provides high low-speed torque for loading operations while allowing the traction and hydraulic systems to be matched to their respective power demands.
The powertrain can be configured for both battery electric and range-extended applications, providing flexibility for different operating cycles, power requirements, and charging conditions.
High Torque for Loading Operations
The traction system combines a high-torque PMSM motor with a 2-speed AMT transmission to provide the wheel-end torque required for loading, digging, and climbing operations.
Independent Hydraulic Drive Motor
A dedicated electric motor independently drives the hydraulic system, providing power for boom lifting, bucket operation, and steering while allowing hydraulic power demand to be managed separately from vehicle propulsion.
2-Speed AMT for Flexible Operation
The 2-speed AMT provides torque multiplication during low-speed loading operations and a higher gear for transport, allowing the traction motor to operate efficiently across different vehicle speeds.
Modular Powertrain Configuration
The modular architecture supports battery electric and range-extended configurations and can be adapted to different wheel loader platforms, hydraulic system layouts, and operating requirements.
01
Traction Motor & 2-Speed AMT Drive System
Designed for 5–7 ton electric wheel loaders, the traction system combines a permanent magnet synchronous motor with a 2-speed AMT transmission to deliver high wheel-end torque for loading operations and efficient power delivery during transport.
Key Features
High Low-Speed Torque
The 2-speed transmission multiplies motor torque during loading and digging, providing the tractive force required for heavy-duty operation.
Two-Speed Operation
1st gear is used for loading and digging, while 2nd gear supports higher-speed transport and site transfer.
Electronic Shift Control
Electronic transmission control manages gear selection and shifting according to vehicle operating conditions.
Forward & Reverse by Motor Control
Vehicle direction is controlled through motor rotation.
Compact Powertrain Design
The integrated motor and AMT configuration provides a compact drivetrain layout that facilitates installation and vehicle packaging.

Range-Extended Electric Wheel Loader Powertrain
For wheel loaders operating for extended hours or in locations where charging infrastructure is limited, a range-extended powertrain provides an alternative to a fully battery-electric configuration.
The traction and hydraulic systems remain electrically driven, while an engine-generator system supplies additional electrical energy to support continuous operation. This architecture reduces dependence on large battery capacity while retaining the responsive torque characteristics and controllability of electric drive.
Engineering Advantages
Reduced Battery Capacity Requirements
A range-extended architecture can use a smaller battery pack than a comparable battery-electric wheel loader, with the engine-generator system providing additional electrical energy during operation. This can reduce battery-related weight, packaging requirements, and upfront system cost.
Extended Operating Time
Continuous electrical power generation reduces dependence on external charging and allows the wheel loader to operate for longer working cycles. This is particularly relevant for high-utilization applications where extended downtime for charging is difficult to accommodate.
Electric Traction & Hydraulic Drive
The traction and hydraulic functions remain electrically driven, providing responsive torque control and independent power management for vehicle propulsion and working functions.
Suitable Applications
- Long-Hour Wheel Loader Operations
- Remote & Off-Grid Sites
- Heavy-Duty Material Handling
- Continuous Production Operations
Recommended When
- Charging infrastructure investment needs to be minimized
- Vehicle operation requires long working hours with limited downtime
- Limited Charging Availability
