Technology
A new approach to motor design and control algorithms that helps us build sustainable and efficient motors and controllers.
Magnet Free Torque
Chara's fundamental new approach to reluctance motor design helps Chara build motors that are as quiet, smooth and powerful as a permanent magnet motors. Chara has developed revolutionary motor platforms in both Switched and Sychnronous reluctance motors.
Novel Stator and rotor configuration in Chara's Switched Reluctance Motors helps in uniform flux distribution that significantly reduces the noise and torque ripple. Chara's SRMs are more power dense than standard SRMs.

Intelligent Controllers
Chara’s proprietary Drive Control FIrmware (DCF) is the brain of our motor controller. The state-of-the-art motor control algorithms are a variant of Field-Oriented Control developed to extract maximum performance from Chara Motors. Model-Based Design (MBD) gives peak motor performance while ensuring optimum efficiency, thermal management and smooth, ripple-free torque delivery.
DCF contains signal processing algorithms and control laws that enable high-bandwidth torque control loops that are executed in real-time. Safety and reliability as per ISO26262 is at the heart of our software and firmware design.
DCF employ self-tests and diagnostics that help in fault isolation and safe-state management. Additionally, DCF supports a stream of up to 50 internal motor parameters for advanced, cloud-based prognosis using IoT.
