If your driving sits below that envelope, the \u003cstrong\u003eDDS26\u003c\/strong\u003e delivers the identical architecture, encoder, processing, connectivity and software at 26 Nm, in a shorter, lighter package.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch3\u003eWho is the DDS39 for?\u003c\/h3\u003e\n\u003cp\u003eFor drivers who want no ceiling on force feedback: heavy GT and open-wheel loads, rally and drift transitions, and long endurance stints where output must stay constant. Its 2,500 W stage and 350 VDC bus at 40 A keep the full 39 Nm available through the fastest direction changes, with zero thermal fade.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference with the DDS26?\u003c\/h3\u003e\n\u003cp\u003eTorque and power delivery only: 39 Nm with a 2,500 W stage at 40 A against 26 Nm with a 1,500 W stage at 25 A, in a slightly longer housing (420 mm vs 380 mm) at 13.5 kg vs 11.1 kg. Encoder, motor technology, TorqueSync processing, connectivity, mounting, software and warranty are identical.\u003c\/p\u003e\n\u003ch3\u003eWhy a 350 V architecture rather than 48 V?\u003c\/h3\u003e\n\u003cp\u003eVoltage defines speed capability and response, current defines torque. As the motor turns faster it generates back-EMF, and a controller can only push current if its bus voltage sits above it. A 48 V system runs out of headroom sooner, so torque falls off at speed and transitions slow down. The 350 VDC bus keeps torque available across a wider speed range and delivers a higher slew rate — precisely what matters when catching slides or hitting kerbs.\u003c\/p\u003e\n\u003ch3\u003eIs 39 Nm manageable?\u003c\/h3\u003e\n\u003cp\u003eYes, with sensible settings. Every force feedback parameter is adjustable in RaceDirector, so you can start lower and build up, with instant profile switching per car and per sim. Safe Torque Off is included, and a rigid cockpit mounting is strongly recommended at this torque level.\u003c\/p\u003e\n\u003ch3\u003eDoes it support iRacing 360 Hz?\u003c\/h3\u003e\n\u003cp\u003eThe DDS39 ships fully compatible with iRacing using the standard force feedback path. The optional 360 Hz mode is not in the day-one build: the control stack already handles high-rate torque processing, so it will be enabled through a firmware and software update once the integration is finalised. No hardware change needed.\u003c\/p\u003e\n\u003ch3\u003eDoes it work with my existing wheels?\u003c\/h3\u003e\n\u003cp\u003eYes, provided they use the Ø70 mm M5 bolt pattern. The ecosystem is fully open: any wheel supporting standard USB connects without adapters or licences, and the quick release slipring carries full data and power, so displays, LEDs and telemetry modules keep working normally.\u003c\/p\u003e","brand":"Sim-Lab","offers":[{"title":"Default Title","offer_id":56018787107141,"sku":"SLA238","price":1999.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0875\/6261\/7157\/files\/Sim-Lab-DDS39-TorqueSync-_-39Nm-Direct-Drive-Wheelbase-Sim-Lab-471509898.png?v=1784910978","url":"https:\/\/thefrenchsimracer.com\/en\/products\/sim-lab-dds39-torquesync-39nm-direct-drive-wheelbase","provider":"The French Simracer","version":"1.0","type":"link"}
