Puck Motor-Controller Operating Region — P4-37

Peak (100 ms) and continuous current envelope vs. bus voltage. Drag the sliders to explore.

Switching Freq 16 kHz
The star knob — every switching loss scales with fsw, collapsing the high-voltage end.
Ambient Temp 25 °C
Shrinks the continuous region as headroom to the target drops. (Peak is unaffected.)
Advanced Mode
Duty Cycle (PWM) 50%
Average conduction duty per FET. ~50% = balanced FOC (the baseline, independent of speed); approaching 100% = a single FET at held-position / stall, where conduction loss up to doubles and the peak envelope derates. Calibration stays pinned at 50%.
Max Puck Temp 100 °C
Ceiling puck temperature for continuous operation — raising it grows the continuous region.
Active-Cooling Uplift 1.25×
Heuristic continuous multiplier for active cooling (not yet back-calibrated).
