Voltage and current are two of the significant parameters in determining the functionality of a Micro DC motor. The voltage rating defines the level of electrical potential needed to drive the motor. In general, micro DC motors can operate on a range of voltages, typically between 1.5V and 12V, with some specialized versions able to handle slightly higher or lower levels. Voltage influences the speed and power output of the motor, with higher voltages generally resulting in higher speed and torque, though the power consumption also increases as a consequence. On the other hand, current is the measure of the motor’s electrical demand. The current drawn by the motor depends on its load and operating conditions, with higher currents typically required for higher-load applications.
