One sweeper. One controller.

DALA Motion officially launches the AM1-S7 Integrated Motor Controller!

In the commercial cleaning equipment industry, manufacturers have always faced two major challenges in production and overall operations: performance and cost. How can they improve machine performance while effectively reducing total vehicle costs in an increasingly competitive market?

DALA Motion's answer is integration and intelligence — making cost reduction and efficiency improvements possible through innovative control technology.

DALA Motion's Commitment to Integrated Control

From XD5 and AM0-T to AM1-S7

As one of the early manufacturers in China to invest in integrated controller technology, DALA Motion has successively introduced two well-established integrated controller platforms: XD5 and AM0-T. These products have helped customers in multiple industries transition from multiple separate controllers to integrated control systems.

Our goal has always been to help customers achieve greater overall machine value at a lower total cost.

Building on years of technical experience and continued investment in commercial cleaning equipment, DALA Motion has developed the next-generation AM1-S7 Integrated Controller.

Following the functional architecture of conventional sweepers, a single AM1-S7 can centrally control up to eight motor channels, covering traction, brush drive, vacuum, side brushes, and multiple linear actuators. It offers a new integrated control option for sweepers and the wider commercial cleaning equipment industry, including cleaning robots.

PART 01 | Integration: Higher Assembly and Maintenance Efficiency

Traditional sweepers typically use one traction controller combined with multiple relays to separately drive the traction motor, brush motor, side brushes, and vacuum motor.

This approach makes vehicle design and wiring more complicated, increases assembly and maintenance costs, and limits manufacturers' production efficiency due to time-consuming and error-prone assembly processes.

With the AM1-S7, a single controller can manage eight motor channels, including traction, brush drive, vacuum, and side brushes. It covers most small- and medium-sized sweeper models currently available on the market.

The main specifications are shown below:

Compared with conventional drive architectures, the AM1-S7 delivers direct benefits to equipment manufacturers:

• Significantly simplifies vehicle wiring and shortens assembly time, improving production capacity and delivery efficiency.
• Reduces potential failure points and assembly errors, making vehicle maintenance more efficient.
• Reduces the number of components required, lowering procurement and inventory management costs.

For manufacturers, this means faster development, faster assembly, and faster delivery — with significant improvements in overall operational efficiency.

PART 02 | Brushless Drive: Longer Runtime and Extended Service Life

Over the past decade, commercial cleaning equipment has predominantly used brushed DC motors. However, their limitations have become increasingly apparent:

• Low efficiency and high energy consumption limit battery runtime.
• Short service life and frequent maintenance, with carbon brushes typically requiring maintenance or replacement after 2–3 years.
• Less refined driving experience, as square-wave control can cause noticeable jerking and higher operating noise.
• Higher overall costs compared with brushless motor solutions.

The AM1-S7 fully supports brushless motors for traction drive, making the transition from brushed to brushless technology more accessible:

• Motor efficiency reaches up to 95%, extending operating time with the same battery capacity.
• Service life is doubled, reducing maintenance and downtime costs.
• Sine-wave control delivers smoother operation and a more comfortable driving experience.
• Brushless motors offer cost advantages over brushed alternatives, helping reduce overall vehicle costs.

By adopting brushless drive technology, manufacturers can significantly reduce component and maintenance costs while improving efficiency, achieving comprehensive optimization of both cost and performance.

PART 03 | Next-Generation Industrial-Grade Architecture: Simplifying Traditional Controller Designs

Commercial cleaning equipment, especially sweepers, often operates outdoors under heavy loads throughout the year. Controller reliability and stability directly affect vehicle costs and the end-user experience.

The AM1-S7 is built on DALA Motion's next-generation direct-connected power topology. It represents a new generation of electric control products driven by fundamental innovations in product architecture and underlying technology.

Compared with previous-generation controllers, the new architecture offers several key advantages:

• 30% fewer components and 50% lower manufacturing process complexity, reducing potential failure points.
• Mean time between failures (MTBF) increased by 300%, helping reduce after-sales and warranty costs.
• Enhanced sealing and thermal management for more reliable operation in dusty, wet, and demanding environments.

Fewer repairs and more reliable manufacturing processes give sweepers greater all-weather operating capability. Rain, dust, and extended full-load operation become easier to handle.

PART 04 | Intelligent Control: A New Era for Sweeper Applications

The AM1-S7 integrates a comprehensive system of capabilities, from hardware protection to intelligent monitoring, creating a robust safety framework for cleaning equipment.

• CAN Connectivity: Built-in CAN communication enables seamless integration with IoT platforms for real-time monitoring.
• Power Interruption Protection: An integrated isolated power supply helps maintain control system stability during unexpected power interruptions and prevents power surges.
• Comprehensive Protection: Built-in overvoltage, undervoltage, overcurrent, overtemperature, and reverse-polarity protection helps prevent electrical faults from damaging the vehicle.
• Operational Safety: A watchdog mechanism and brake interface with short-circuit protection provide additional safeguards to keep the vehicle controllable in emergency situations.
• Intelligent Downhill Speed Control: When the accelerator is released on a slope, the controller automatically maintains a low downhill speed, helping prevent safety incidents.

From distributed control to all-in-one integration, from brushed to brushless drive, and from reactive maintenance to proactive protection — the AM1-S7 represents a significant step forward in cleaning equipment control technology.

It addresses the practical challenges faced by sweeper manufacturers while embracing the industry's key trends of integration, intelligence, and cost optimization. Whether used in sweepers, scrubber dryers with brushless traction motors, or cleaning robots, the AM1-S7 offers a versatile solution to help manufacturers strengthen their competitiveness.
