Motor Phase Current Waveform (In Sine or six-step mode output torque = Motor KT* Drive IFB) |
Pure sinusoidal or 6-step, depending on feedback device. |
Motor Shaft Torque (Ignoring motor magnetic saturation) |
|
Peak (hot motor winding) Multiply KT * 1.06 for cold motor winding (AKM or PMA motors). |
KT (N-m/ARMS) * Drive Ipeak (ARMS) |
Instantaneous |
KT (N-m/ARMS) * IFB (ARMS) |
