What is a VESC controller?

A VESC (Vedder Electronic Speed Controller) is an open-source brushless motor controller running VESC firmware. It uses Field-Oriented Control (FOC) for smooth, efficient, programmable control of BLDC and PMSM motors, configured via VESC Tool.

What is the difference between VESC and a standard ESC?

Unlike closed-firmware ESCs, VESC exposes every parameter (FOC, current limits, regen, throttle curves) for tuning, supports sensored and sensorless motors, and offers telemetry and scripting - ideal for custom EV and robotics projects.

What VESC current rating do I need (200A, 1000A or 2000A)?

Size by your motor's phase-current demand and application. 200A-500A VESC controllers suit ebikes, scooters and light robotics; 1000A-class units power high-performance eskate, EUCs and small EVs; 2000A VESC controllers target extreme builds such as electric motorcycles and industrial drives. Always leave headroom above your battery's fully-charged voltage.

Are ChatRobotic VESC controllers customizable / available for OEM?

Yes. ChatRobotic is an ISO 9001 & ISO 14001 certified manufacturer offering OEM/ODM VESC controllers, custom firmware, enclosure design and PCB assembly for 200A-2000A applications.
