Are the voltage requirements (0-36V line to neutral) specified as peak value or rms? And are we on the right path, that the given voltage is the sinusoidal fundamental oscillation of the trapezoidal back EMF of one motor coil?
The 0-36V specification is rms value of the fundamental component. These specifications are ‘nominal’. Depending on the team’s particular control strategy (speed, torque, current, power, MTPA, etc), the voltage fundamental component may be higher or lower. The actual test conditions that will be evaluated will include measurements of voltage and current simultaneously to evaluate the power delivered to the motor.
