Representative parameter model
Kt = 0.075 N·m/A, phase resistance = 0.22 Ω, gear ratio = 30:1, assumed gearbox efficiency = 72%, thermal resistance = 1.8 K/W. Motor torque is output torque ÷ (ratio × efficiency); current = motor torque ÷ Kt; copper heat = I²R × duty; winding temperature follows a first-order thermal response. The torque-speed curve is a simplified linear envelope. Values are illustrative and should be replaced with a chosen motor’s datasheet before making engineering decisions.
