A Motor Calculator is an engineering tool designed to help users analyze and determine the performance characteristics of electric motors. Users input key parameters such as voltage (V), current (A), power (kW/HP), efficiency (%), speed (RPM), and torque (Nm/lb-ft) to calculate unknown values or verify motor specifications. The calculator can determine power consumption, energy efficiency, operating costs, and mechanical output based on these inputs. Advanced versions may include features for three-phase motor calculations, load analysis, or comparison between different motor types (AC/DC, servo, induction). This tool is essential for engineers, technicians, and hobbyists working with motor-driven systems.
