Using more than one motor in an EV (Electric Vehicle) powertrain enhances the vehicle’s torque, acceleration, and speed capabilities. A more tractive force produced by the electric powertrain requires more electric current from the battery. In modern EVs, mechanical power production can be approached to the wheels reducing the mechanical losses in the transmissions. It is the case with multiple-motor powertrains. Several advantages regarding vehicle control, physical performance, and energy efficiency improvement are obtained. In the current study, a BLDC (brushless dc) motor is investigated from the efficiency point of view to build a multiple-motor powertrain. A new methodology uses analytic calculations, simulations, and physical measurements. A powertrain with three identical motors results in a new vehicle configuration. Each motor's energy consumption improvements are analyzed following a normalized testing procedure. The results are compared with those of a single-motor powertrain.

“…6. -Model for motor capabilities investigation [35] The "w" block generates different speed levels to investigate all operational areas of the motor. Depending on the speed, the "Phase Reference Currents" block creates the rectangular shape of the phase currents of the motor, and the "Motor Supply" integrates the DC power source, the commutation pulses generation, and the inverter.…”

“…In this context, the actual paper continues to investigate the capabilities of permanent magnet motors. If control improvements like the usage of phase advance and dwell control generate better performance in terms of speed [34] and energy efficiency [35], in this case, the investigation concerns the usage of a BLDC (brushless DC) motor in a multi-motor powertrain. In [7] the analysis regards the usage of multiple smaller motors instead of a single motor covering the whole operating points.…”

In an EV (Electric Vehicle), the more tractive force produced by the electric powertrain in fact requires more electric current from the battery. The question is how efficiently the stored energy is used, as for modern EVs, the ability to move over a greater distance represents an important issue. Of course, it can be best confirmed by physical measurements on the vehicle, but before, the analytic calculations and the simulations are important to certify the choices. In this context, the actual paper presents the analysis of the capabilities of a BLDC motor powertrain. A new method is used in the determination of the number of identical motors needed to participate in the powertrain, based on the efficiency map of the individual motor.
