Motor module#

This module includes an electric motor model that can be used to compute rotation speed, torque efficiency based on the characteristics.

Physical background#

The model can be represented as shown below:

Electric diagram

It considers two resistors, one inside the motor and the other one in the power source in addition to the motor itself.

A coefficient \(K_v\) is used to bind the rotation speed with the electromotive force \(E\):

(1)#\[E = \frac{\omega}{K_v}\]

All the relations in the module derive from the electric equations behind this representation.

Database source#

Some motor characteristics are based on the technical documentation of EMRAX. The other ones are fictional examples.
