WebDC Motor. A DC motor is an electrical machine that converts electrical energy into mechanical energy. In a DC motor, the input electrical energy is the direct current which is transformed into the mechanical rotation. In this session, let us know what is a DC motor, types of DC motor and their applications. Table of Contents: WebYou can measure the holding torque, by mounting a little lever to the motor (e.g. r =10 cm=0.1m long) which the motor pushes onto e.g. a kittchen scale. The mass m (in Kilograms, e.g. m =34g=0.034kg) measured by the scale can then be used to calculate the force, which is F = m * g, where g is the earth gravity constant (approx. 9.81 m/s²). scrapbooking for mac
