Advanced Testing Solutions for Electric Powertrain Systems

ACS’ electric powertrain systems designed for electric motors (E-motors) and electric driveline testing are sophisticated solutions engineered to assess and verify the performance, efficiency, and reliability of electric motors and drivelines in electric vehicles. These systems play a crucial role in advancing the development, testing, and improvement of electrified powertrains within the automotive and aerospace industries.

During our testing process, the electric motor and driveline components undergo a spectrum of simulated conditions to assess their performance, efficiency, and durability. This involves evaluating their responsiveness to various loads, speeds, and environmental factors. The primary objective is to ensure that these components not only meet specified requirements and industry standards but also exhibit resilience to the demands of our clients’ real-world applications.

ACS specializes in engineering, integrating, and constructing Alternating Current (AC) and Permanent Magnet (PM) dynamometers alongside electric powertrain dyno control systems. Tailoring these solutions to your unique needs, testing goals, and Unit Under Test (UUT) specifications, our team guarantees that the design, build, and integration of your electric dynamometer solutions align with current objectives and future advancements.

Our experience with complete dynamometer systems ensures seamless development and integration no matter our client’s unique applications. This range includes motors and riser bases, guards, torque transducers, connection cables, battery simulators, UUT power supplies, power analysis, and high-voltage interface panels in single- or multi-axis configurations. With goals and components specified, it’s possible to assemble and integrate into a test cell, build as a complete, stand-alone test stand, or integrate as part of an in-process or end-of-line manufacturing test station.

Customized Solutions Backed by Industry Expertise: SINAMICS S120

We make sure our clients are prepared for future growth and innovation through partnership with Siemens, specifically their SINAMICS S120 drive system. The drive system’s plug-and-play configuration means that dyno solutions are highly scalable and adaptable. SINAMICS S120 modular high performance and servo drives are designed for precision motion control for high-performance applications in mechanical and systems engineering. Your build benefits from their family of modular drives, offering precise control of electric motors, no matter the industrial setting. Most notably, S120 drives are vastly flexible without sacrificing efficiency, with functionalities adjustable to single and coordinate drives, vector or servo functionalities, and free combination or separation of power and control performance, on top of state-of-the-art systems architecture and digital communication options. Since the SINAMICS S120 drive system is part of Siemens’ extensive portfolio of drive technologies and automation solutions, our clients are guaranteed universal, standardized safety backed by ongoing, consistent advancements to their embedded software and data acquisition methods.

Prepare for Any “What If”

We work with your team to define and implement a dynamometer testing solution that meets your requirements. To help you get started, we’ve developed a specification questionnaire that addresses types of applications, custom equipment, controls, and any “what ifs” you may encounter when testing electric vehicle drivetrains and powertrain systems. Application areas are unique to the products and environments needed by our clients, including options such as:

  • Production testing of transaxle and drive motor systems
  • Electrified axles, gearboxes, transmissions, accessories
  • Component and system development and performance verification
  • Ground-vehicle and aerospace electric powertrain dyno testing
  • Powertrain control system and inverter development
