The Sevcon Gen4 Size 8 is a three-phase AC motor controller designed to operate high-power permanent magnet synchronous motors (PMSM) and AC induction motors (ACIM). It features advanced flux vector control to optimize motor efficiency and torque delivery across a wide speed range. Hardware Variations
The Size 8 utilizes a high-density, sealed Ampseal 35-way connector for all control, sensor, and communication inputs. Pin 1 / Pin 2: CAN High and CAN Low communication lines. It features advanced flux vector control to optimize
Connect directly to the main EV battery pack via an external high-voltage fuse and a pre-charge contactor circuit.
Before applying high voltage, ensure your low-voltage logic circuit is isolated and correctly wired: Connect directly to the main EV battery pack
Before installation, understanding the "DNA" of the Size 8 is essential.

It is critical to note that while basic datasheets are publicly available, the full technical applications reference manual is often restricted. Historically, Sevcon and BorgWarner have required an NDA (Non-Disclosure Agreement) and direct contact with sales to release the complete 130+ page manual. This guide compiles information from the standard versions of the public manual and application notes to help you navigate the system.
