| Controller Parameters | ||
| Please specify the custom motor controller's battery and phase current limits as well as the effective mosfet and lead resistance | ||
| Battery Current Limit (A) | ||
| Phase Current Limit (A) | ||
| Effective Resistance (Ω) | ||
| Throttle Type | ||
| Motor Parameters | ||
| Please specify the motor parameters below: | ||
| rpm/V = Nm/A Kv: Motor winding constant (Nm/A = 60/2Pi/(rpm/V)). | ||
| Rmotor: Room-temperature phase-to-phase winding resistance (Ω) | ||
| Lmotor: Phase-to-phase winding inductance (mH) | ||
| poles: Effective magnetic pole pairs, ie motor pole pairs times the gear ratio to the wheel | ||
| a0: Hysteresis torque of the motor in Nm. You can derive it from the no-load current at low speeds | ||
| a1: Eddie current torque of the motor, (N-m/(Rad/sec)). You can derive it from the slope of the no-load current vs. rpm | ||
| t: Gear/transmission loss of the motor. If you have a direct-drive motor, it would be 0.00. For a 3% gear loss in a geared motor, set it to 0.03 | ||
| freewheel: Check this checkbox if the motor has an internal freewheel and can't do regen | ||
| Battery Parameters | ||
| Please specify the open-circuit voltage, internal resistance in ohms, and capacity in amp-hours below: | ||

| Ah | ||
| Wheel Size: | ||
| Please specify the full wheel diameter below: | ||
| Inches | ||

| Frame Parameters | ||
| Please specify your vehicle's air drag and rolling drag coefficients. There is an excellent online tool at http://kreuzotter.de for getting the CdA and Cr values for a wide range of bicycle geometries and riding positions. Be sure to select the metric units option. | ||

| Human Power | ||
| Typically people riding casually will be putting out 100-150 watts, while competitive cyclists will sustain 300-400 watts. Ride an excercise bike at the gym to see your own output. | ||
