Engineered for high-capacity L5 cargo fleets and demanding commercial routes, the Voltworks V-CTRL-FOC-3500W serves as the heavy-duty control center for 3.5 kW electric powertrains. By combining an expanded, high-amperage MOSFET power stage with advanced Field-Oriented Control (FOC) software algorithms, it delivers smooth, linear acceleration and high low-end torque while maximizing battery energy conservation during maximum payload operations.
Key Features & Benefits
Ultra High-Capacity MOSFET Power Stage:
Constructed with industrial-grade MOSFET arrays capable of handling sustained high phase currents with low internal resistance ($R_{DS(on)}$). This minimizes thermal buildup and guarantees high reliability during steep incline climbs and continuous heavy-load delivery routes.
Advanced Field-Oriented Control (FOC) / Sine Wave Technology:
Delivers quiet, vibration-free motor operation with minimal torque ripple, providing seamless low-end torque delivery compared to conventional square-wave controllers.
High Controller Efficiency (>95% Peak Efficiency):
Reduces conversion heat losses under high power draw, maximizing per-charge driving range and preserving battery health over long operating life cycles.
Multi-Tier Drivetrain Safety Suite:
Monitors power flow continuously with built-in real-time protections, including Over-Current Protection (OCP), Over-Voltage & Under-Voltage Protection (OVP/UVP), Over-Temperature Protection (OTP), and Phase Short-Circuit Safeguards.
Regenerative Braking Capability:
Recovers kinetic energy during downhill coasting and braking, feeding power back into the battery pack to extend operational range while reducing mechanical brake pad wear.
Heavy-Duty All-Weather Aluminum Housing (IP65/IP67):
Housed in an extruded aluminum enclosure designed for high passive heat dissipation, protecting internal components against road dust, monsoon rain, and severe vehicle vibration.

VoltWorks Technologies Private Limited is an Indian clean-tech mobility and hardware startup focused on designing, engineering, and manufacturing advanced electric vehicle (EV) powertrain systems. Founded by alumni from top premier institutions like the Indian Institutes of Technology (IIT), VoltWorks specializes in delivering integrated motor, controller, and energy conversion systems tailored for light commercial and passenger electric vehicles in emerging markets.
Core Focus & Expertise
Integrated Powertrain Engineering: Rather than delivering isolated parts, VoltWorks engineers cohesive powertrain ecosystems—combining high-efficiency electric motors, advanced controllers, and custom software stacks.
Field-Oriented Control (FOC) Innovation: The company's key competitive advantage lies in its proprietary Field-Oriented Control (FOC) motor controllers. These optimize torque delivery, improve energy efficiency by over 93%, and prolong battery pack lifecycles under intense daily usage.
R&D & Academic Partnerships: Incubated under the FIRST foundation at IIT Kanpur, VoltWorks actively collaborates with leading technical institutes (including IIT Madras and NIT Silchar) to bridge research-grade EV innovations into commercial production.
Mission & Market Position
VoltWorks aims to accelerate the transition to sustainable urban transportation by providing robust, affordable, and high-efficiency powertrain components built specifically for harsh local operating conditions—such as extreme heat, heavy payloads, monsoon road water splash, and stop-and-go commercial routes. Their primary target market includes original equipment manufacturers (OEMs), fleet aggregators, and retrofitters in the L3 (E-Rickshaw/E-Passenger) and L5 (Light Commercial EV) segments.
