The Phaserunner is a compact state-of-the-art field oriented motor controller (FOC) from Grin Technologies based around the sophisticated control electronics from Accelerated Systems Inc. of Toronto. It is ideally suited for running brushless motors for electric vehicles in the 500-2000 watt power range, and once you have experienced the smooth response of a FOC with a torque throttle it's hard to go back to a the setup you had before.
This controller was designed as a universal device that can fit on almost any bicycle frame and handle almost any motor system. You can power it from a 24V battery or a 72V battery, and run your phase current to peaks of over 90 amps, though the continuous current capability without additional heatsinking is typically 45-50A. The wiring is paired down to the bare basics for a nice clutter-free installation; including a throttle plug, a Cycle Analyst plug, cable to your motor, and a cable to your battery pack.
Remote on/off switch compatible
Direct plug for both V2 and V3 Cycle Analysts
Proportional regen available through throttle signal or stand alone wire
Works both Sensored and Sensorless, and even with very high eRPMs
Waterproof, 100% potted electronics
Fully programmable parameters (regen voltage, max phase and battery currents etc.)
Field Weakening allows you to run motors faster than normal back-emf limit
Higher motor efficiency at low speeds / high torques
Torque based throttle command (no twitchy throttle with powerful system)
Operating voltage range from 20V to 90V (21S Li-Ion, 24s LiFe)
Automatic thermal rollback to prevent controller overheating
