DC motor controllers are essential components in battery-powered vehicles, managing not only traction motors but also lifting, steering, pump and auxiliary motor functions. From pallet trucks and stackers to utility vehicles and compact electric mobility systems, the right controller helps deliver smooth operation, reliable performance and efficient power management.
Battery-powered industrial vehicles rely on more than a single motor function. While traction is often the first application that comes to mind, many vehicles also require separate motors for lifting systems, hydraulic pumps, steering and other auxiliary functions.
This makes the DC motor controller a central part of the vehicle architecture. Its role is to manage motor speed, current and torque according to the demands of each function while maintaining reliable operation under changing loads.
Why DC Motor Controllers Matter in Electric Vehicles
In electric and battery-powered vehicles, brushed DC motors are still widely used in applications where high starting torque, straightforward control and robust operation are important.
A DC motor controller regulates how electrical energy from the battery is delivered to the motor. Depending on the application, the controller may be responsible for:
- Vehicle traction
- Hydraulic pump operation
- Lifting functions
- Electric steering
- Auxiliary motor functions
- Controlled acceleration and deceleration
The same basic control principle can therefore support very different vehicle functions.
Traction Control: Moving the Vehicle
Traction is one of the most common applications for a DC motor controller.
In equipment such as:
- Electric pallet trucks
- Walkie stackers
- Tow tractors
- Floor cleaning machines
- Utility vehicles
- Industrial transport vehicles
the traction controller manages the drive motor according to accelerator input, load conditions and vehicle commands.
A well-matched controller helps provide smooth acceleration, predictable torque and controlled vehicle response. In applications where operators frequently start, stop and maneuver under load, this directly affects drivability and system reliability.
Lifting and Hydraulic Pump Control
In material handling equipment, vehicle movement is only one part of the job.
Electric pallet trucks and stackers also need to lift loads, which is typically achieved through a hydraulic system driven by an electric motor.
Here, a DC motor controller can be used to manage the hydraulic pump motor, controlling when and how the pump is activated according to the lifting command.
This means the controller can support functions such as:
- Fork lifting
- Platform elevation
- Hydraulic pump operation
- Controlled load handling
For material handling applications, this is especially important because the pump motor may need to deliver high current for short periods while lifting a load.
Steering and Auxiliary Motor Functions
DC motor controllers can also be used beyond traction and lifting.
Depending on the vehicle architecture, brushed DC motors may be used for:
- Electric steering systems
- Wiper motors
- Cooling fans
- Pumps
- Small auxiliary mechanisms
These functions may not require the same continuous power as traction, but they still benefit from controlled motor operation and reliable current delivery.
This is why vehicle designers often need to consider several motor control requirements within the same platform rather than thinking only about the main drive motor.
One Vehicle, Multiple Motor Control Tasks
A simple electric pallet truck is a good example of this.
The same vehicle may include:
- A traction motor to move the vehicle
- A hydraulic pump motor for lifting
- A steering motor depending on the vehicle design
- Additional DC motors for auxiliary functions
Each motor performs a different task, yet all require controlled and reliable power delivery.
For OEMs and system integrators, choosing the correct controller therefore means evaluating more than motor power alone. Battery voltage, continuous current, peak current, duty cycle, communication requirements and vehicle function all need to be considered together.
What Should You Look for in a Vehicle DC Motor Controller?
For battery-powered industrial vehicles, several factors are especially important:
- Voltage compatibility with the vehicle battery system
- Rated and peak current capability
- Reliable operation under variable loads
- Regenerative braking support, where required
- Configurable inputs and outputs
- CAN communication
- Diagnostic capabilities
- Environmental protection
- Compact integration into the vehicle architecture
A controller that matches both the motor and the actual duty cycle can improve vehicle behavior and simplify system integration.

The SVD-24-90 provides 50 A rated output current and 90 A peak boost current, while the SVD-24-125 provides 70 A rated output current and 125 A peak boost capability. Both models are specified at 95% efficiency.
This makes the SVD Series suitable not only for traction applications, but also for other brushed DC motor functions within battery-powered vehicles, depending on the motor and system requirements.
Typical Application Areas
The SVD Series is positioned for applications including:
- Electric pallet trucks
- Walkie stackers
- Tow tractors
- Floor cleaning machines
- Utility vehicles

- Material handling equipment
- Automated Guided Vehicles (AGVs)
- Battery-powered service vehicles
Within these platforms, DC motor control may be required for traction, hydraulic lifting, steering or auxiliary systems.
More Than Just Traction
A vehicle motor controller should not be viewed only as a traction component.
In modern battery-powered machines, different DC motors may perform very different tasks within the same vehicle. Traction, lifting, steering and auxiliary systems all depend on controlled power delivery and reliable motor management.
Choosing the right controller starts with understanding the actual function of the motor, the electrical requirements of the system and the vehicle’s operating conditions.
For manufacturers and integrators working with brushed DC motors, a flexible motor controller platform can simplify development and support multiple functions across the same vehicle family.
