Note: EV motors provide maximum torque from 0 RPM to base speed, then maintain constant power by reducing torque. This gives EVs their characteristic instant torque feel. Tesla Model 3 motor: ~350 N-m, 12,000 RPM max.

Reference

Below Base Speed: Torque = Peak Torque (constant) Above Base Speed: Torque = Peak Torque × (Base RPM / RPM) Power (kW) = Torque × RPM × 2π / 60 / 1000 Peak Power occurs at Base Speed transition Power (hp) = kW × 1.341
