Accelerated Systems Inc. (ASI), a leader in intelligent electrification and motor control solutions, is advancing e-mobility with its next-generation AC-Permanent Magnet (AC-PM) motor technology. Engineered to deliver exceptional torque density, high efficiency, and compact design, ASI’s platform empowers OEMs to build lighter, faster, and more efficient electric systems for light electric vehicles (LEVs), e-motorcycles, scooters, and outdoor power equipment.
Engineering Precision Meets Power Density
At the core of ASI’s new AC-PM motor technology lies a design philosophy centered on performance optimization across the full operating envelope. By combining finite element magnetic analysis (FEM), field-oriented control (FOC) algorithms, and integrated sensor feedback, the system delivers smooth torque output and exceptional thermal stability even under demanding operating conditions.
Key Performance Attributes:
High Torque Density: By leveraging rare-earth permanent magnets with optimized pole configurations, ASI’s AC-PM motors deliver higher torque per amp, allowing downsized systems without sacrificing output.
Superior Efficiency: Reduced rotor losses and optimized back-EMF waveforms minimize energy waste, extending range and runtime, crucial for battery-powered systems.
Dynamic Responsiveness: Integrated control logic ensures instant torque response, smooth acceleration, and precise regenerative braking, improving ride feel and control.
Thermal Robustness: Advanced stator winding designs and precision cooling management enable sustained operation across high ambient conditions typical of industrial and mobility environments.
Quiet Operation: Magnetic circuit symmetry and advanced motor control reduce torque ripple and acoustic noise, essential for consumer comfort in e-scooters and compact EVs.
A Scalable Platform for Diverse Applications
ASI’s AC-PM motors are built for flexibility and the same architecture can be tuned for high-speed e-bikes, high-torque utility carts, or hybrid commercial equipment. Combined with ASI’s proprietary motor controllers and vehicle control modules (VCMs), OEMs can achieve complete drive system integration with intelligent communication and diagnostics.
This system-level design approach allows:
- Seamless integration with CAN bus and LIN vehicle networks.
- Optimized motor-controller co-design, reducing EMI and improving thermal distribution.
- Modular firmware updates for customized torque curves, regenerative profiles, and fault management strategies.
Unlike conventional induction motors, permanent magnet AC machines use magnetic fields generated by embedded magnets rather than induced currents — drastically improving power density and efficiency. This translates into better acceleration, lower power draw, and higher reliability, particularly valuable for applications where energy efficiency directly determines range or productivity.
By integrating this with ASI’s advanced vector control algorithms, manufacturers can precisely regulate torque and flux, allowing high efficiency at both low and high loads. The result is a system that performs efficiently across urban stop-and-go conditions as well as long-duration industrial duty cycles.
ASI provides complete customized electrification ecosystems. From concept to production, the company supports customers with system modeling, prototyping, and mass manufacturing. Its vertically integrated design process allows rapid customization of motor geometry, magnet materials, and control firmware to meet specific powertrain requirements.
