The SiliXcon SC 1040 is a programmable electric vehicle motor controller, also known as an electronic speed controller (ESC). It runs on a 20S lithium battery pack and supports up to 84 V of operating voltage. This controller belongs to the ESC3 family, SC series. It drives brushless DC motors as well as every other type of electric motor.
The SC 1040 is built for electric motorcycles, karts, scooters, e-surfboards and jet boards. In addition, it suits industrial drives, automotive drives and marine propulsion systems. It delivers 12,600 W of continuous power and 18,000 W of peak power. Phase current reaches up to 250 A RMS, which is motor phase current rather than battery current.
This is an OEM component for engineers, workshops and manufacturers. You pair it with a suitable motor and a 20S battery pack. Because the unit is programmable, you configure the parameters before operation. The compact aluminium housing makes integration straightforward in tight builds.
Key Benefits
- 20S lithium battery, up to 84 V – 72 V DC nominal voltage across 20 cells in series.
- 12.6 kW continuous power – sustained 60-minute rating with a BLDC motor.
- 18 kW peak power – short 10-second burst mode for acceleration.
- 250 A RMS phase current – high power density inside a compact housing.
- Regenerative braking – energy returns to the battery during deceleration.
- Smooth start-up – even motor acceleration from zero RPM.
- Lightweight aluminium case – strong performance-to-weight ratio and easy mounting.
- Advanced control algorithms – stable operation plus built-in protections and diagnostics.
Who Is This Controller For?
The SC 1040 handles automotive and industrial motor control tasks. Moreover, it fits high-end sport motorcycles, electric bicycles, electric surfboards and scooters. Karting builders also use it where 84 V systems are required.
Beyond vehicles, the unit works in combustion engine starter-generators. Other application areas include professional drones and RC models. It also serves research and development projects as well as servo control.
Its compact dimensions help in systems where space is limited. Therefore, builders choose it for tightly packaged frames and hulls. Marine drives benefit from the same power reserve in a small footprint.

Why Choose the SC 1040?
The 1040 is the most powerful version in the SC series. Its 400 A peak current is the highest of the three, ahead of the 0640 and 0840. It also carries the highest voltage ceiling at 84 V DC.
Power loss stays at 120 W across the whole series. That figure holds even as the 1040 handles 18,000 W in burst mode. As a result, you gain headroom without a thermal penalty compared with the smaller versions.
Advanced control algorithms keep the motor stable under load. Diagnostics and protection functions support safe commissioning. Programmable parameters let you tune the drive to your specific motor and chassis.
