Customer ServiceBattery-powered motor applications need careful design work to match motor performance and power-consumption profiles to the battery type. Optimal motor and battery pairing relies on the selection of an efficient motor as well as a battery with the appropriate capacity, cost, size, maintainability, and discharge duration and curve.
One key motor performance parameter to consider in a battery-powered application is efficiency. Maximizing motor efficiency helps minimize the required power capacity and hence the size and cost of the battery solution. For this reason, brushless DC (BLDC) motors are preferred over brushed DC motors but are typically higher in price.
Conversely, if the motor is rated at 1.5V using a 3V battery runs the risk of immediate damage to the motor (as would anything above the Maximum Operating Voltage). The reduced voltage causes motors to turn slower. This reduces the torque handling capabilities for DC and gearmotors, whilst causing vibration motors to vibrate less.
Optimal motor and battery pairing relies on the selection of an efficient motor as well as a battery with the appropriate capacity, cost, size, maintainability, and discharge duration and curve. Battery-powered AGVs for automated warehousing require brushless dc motors engineered for top efficiency.
Motors draw more current when they start (to overcome the inertia of the mass or friction in gears) than during normal operation, therefore they will reduce the battery life more than normal operation.
Batteries 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).
