Secondary or Derivative Characteristics

The specifications of the DC motors determine some parameters that are derived or can be considered related to fundamental requirements such as speed, voltage and torque, for example. Generally, manufacturers of this type of motor recommend that the output power in units be in CV or HP. It should be noted that in order to convert a calculated value of power from units of watts to units of HP, it is necessary to divide the power in watts by 746.

The current produced in a direct current motor T2A533081S must heat it so that it is capable of causing a dissipated power, also called porpdis. The value of pdis is directly related to the total resistance of the system, which basically consists of the resistance of the entire motor assembly, including the friction losses in the stator and the rotor. A common and important feature when referring to direct current is the rated output power, which represents the torque process by the motor speed. Therefore, the maximum output power must be reached when the motor reaches 50% of the unloaded speed and 50% of the stop torque.
