Why siliXcon
How siliXcon Compares
A recurring customer question is simple — how are you different from the competition? Below is a feature-by-feature comparison reflecting the engineering choices that have shaped our motor controllers over the last 15 years.
What actually sets us apart
The technical detail below matters — but here is what it means for your project.
Physics is our only limit
No artificial slopes, forced ramps or pre-computed caps. Every command runs as fast as the hardware allows — the controller derates only on real physics (temperature, current, voltage, RPM), never on guesswork.
Up to 4x more compact
The same power rating in roughly a quarter of the size of comparable controllers, thanks to an uncompromising protection system.
Application & customization
A configurable application platform with hundreds of ready-made modules — and dedicated custom (OEM) firmware on the same hardware whenever your project needs something unique.
500+ open parameters
Motor, drive, protection, application and connectivity layers are fully exposed to the integrator — no black boxes, no locked features.
Feature-by-feature comparison
Typical competition versus the siliXcon approach, across the fundamentals.
Drive & motor control
A single algorithm hard-wired into the product (FOC or BLDC); switching requires a different hardware SKU.
Three selectable algorithms on the same hardware — FOC for precision down to zero speed, BLDC for robustness, and high-speed BLDC for extreme RPM.
Tuned for a narrow window of motor parameters; high-RPM, low-inductance or reluctance motors often need a different product or are unsupported.
Drives virtually any 3-phase motor — PMSM, BLDC, ACIM, reluctance; inductances down to units of uH and speeds up to 300 krpm, with native field weakening and MTPA.
No torque at zero RPM, requires rotor pre-positioning and extremely sensitive startup tuning.
Near full torque at zero RPM, seamless startup, smooth go-through-zero and instant direction reversal — no pre-positioning, no startup tricks.
Pre-computed slopes, forced filtering and ramping, with artificial limits around the sensorless region.
Real-physics derating only — nothing is pre-computed. Every command is executed as fast as the hardware allows, with full dynamics through the sensorless region.
Traction or industrial-servo product lines, rarely both. Servo-grade precision usually requires a dedicated, lower-power product.
Servo-grade speed, torque and position control on the same controller — full traction-class power electronics combined with precise low-speed and standstill behavior.
A single, low-level command interface — typically just duty cycle for BLDC products or a torque setpoint for FOC products. Everything else is the integrator's problem.
8+ runtime-selectable command mappings on the same firmware — from raw duty cycle and torque, through speed, position and slip control, to full-vehicle command profiles. One platform powers large drones, industrial AGVs and EVs alike.
Drive can only engage at standstill or along the command direction; anything else can destroy the power stage.
Engage or disengage at any time, any direction, any RPM — even a power cycle while spinning at nominal RPM recovers seamlessly.
Back-driven motors and sustained regenerative operation are unhandled and routinely damage the inverter.
Always seamless four-quadrant operation — motoring, generating and back-drive at any operating point.
Power, sizing & protection
Exaggerated short-burst marketing numbers, often just U x I on paper or estimated from datasheets.
Every rating is bench-measured under real load and characterized across the operating envelope — if it is in the datasheet, it is verified on hardware.
The mechanical envelope grows roughly linearly with rating, because the design has no margin without bulk.
Cross-platform engineering and an uncompromising protection system deliver the same rating in roughly 1/4 of the size of comparable competition.
Limited or single-layer protection; an unexpected short, overvoltage or sensor glitch can take the whole power stage with it.
Ultra-fast short-circuit protection at the gate-driver level, multi-layer over/under-voltage protection and continuous self-diagnostics.
Configuration & integration
A limited, fixed set of configurable parameters; non-trivial changes require vendor support.
500+ exposed parameters across motor, drive, protection, application and connectivity layers — fully accessible to the integrator.
Fixed input type per product family — analog-only, PWM-only, or CAN-only.
The same hardware accepts analog (0-10 V, 4-20 mA), digital, servo PWM and CAN/UART commands — selectable in firmware.
Fixed, industry-specific firmware preloaded by the vendor; deep changes require a different product or are not offered.
A configurable application platform with hundreds of ready-made modules, plus dedicated OEM applications on the same hardware.
Diagnostics, lifecycle & safety
Limited error codes, often with no live insight into the controller state.
Live telemetry via siliWatch, a full diagnostic report, per-protection derating breakdown and detailed event logs.
Update procedures often require returning the unit or specialized service tooling.
Remote firmware and parameter updates over standard interfaces — a normal after-sales workflow, even on units already in the field.
A datasheet plus an integration guide, with most know-how locked behind support tickets.
Full firmware, hardware and software documentation publicly available, including FAQs, guides and an AI assistant.
The competition column is industry-agnostic — averaged across the brushless controllers we have benchmarked over the years. Competing products usually specialize in a single industry (RC, EV, e-bike, industrial servo, drones, marine) and may beat this average in their niche. The matrix is scoped to our motor controllers, not to siliXcon as a whole.
The real difference
One platform — from first prototype to series production.
The biggest advantage isn't any single row above. Every siliXcon controller — from an evaluation unit to the largest 800 A class — shares one firmware codebase, one parameter tree, one toolchain and one protection philosophy. Move a project up in power and your parameters, features and integration come with it. That continuity is the moat a feature table can't fully show.
