Customer ServiceBatteries also see a decrease in terminal voltage as the output current (load) increases, which also negatively impacts motor speeds at higher torque loads. These factors do not consider the characteristics of the motor winding itself, where output speed decreases as the motor load increases, even with constant battery voltage (see Graph 1, below).
Power Requirements In any electric motor application, the desired equipment performance dictates the power requirements of the motor. The rated power of the motor is calculated from the combination of speed, torque, and duty cycle of the application that in turn establishes the critical voltage, current, and capacity requirements of the battery.
The voltage of a car battery can range from 12 to 14 volts. It is essential that your car battery has the correct voltage level to maximize the performance of its electrical systems. Low voltage levels can cause a wide range of issues, including difficulty starting the car, lower fuel economy, and slower acceleration.
An essential criteria in battery selection is making sure that the battery will not only supply the motor’s voltage and current requirements when fully charged, but also continue to meet those requirements as it approaches full discharge.
If the armature motor voltage is changed, speed and torque also proportionally change. The relation between the speed without load (n0) and armature voltage (U) is given in the following equation:
