The starter motor typically has a rated voltage of [X] volts. This voltage rating is designed to match the electrical system of the excavator's engine. For example, it might be a 24 - volt system, which is a common voltage used in heavy - duty equipment to provide sufficient power for starting the engine.（Rated Power）
The rated power of the starter motor is [Y] kilowatts (kW). This power rating determines the motor's ability to generate the necessary torque to crank the engine. The power is calculated based on the voltage and current requirements during the starting process and is designed to ensure a smooth and efficient engine start.（Current Consumption）
During the starting process, the starter motor may draw a maximum current of [Z] amperes (A). The current consumption depends on factors such as the engine's compression ratio, temperature, and the load on the starting system. The high - current draw is usually for a short period during engine cranking to provide the necessary torque.
