Direct current motors are machines which produce shaft speed and torque by converting electrical power into rotating power.
The speed of the motor is determined by the supply voltage and the torque is produced as a result of the current interaction with
a magnetic field. The magnetic field can be produced with either electro-magnets or permanent magnets.
There are many DC motors that utilize variations of both styles.
“ Commutation” constantly changes the position of the rotor field
in relation to the stator field to maintain the maximum amount of available force or torque that the motor can produce. To
improve performance and reduce size, replace the wound field with permanent magnets. Another key advantage to the perma-
nent magnet style, which has a constant magnetic field, is the linear relationship between speed and torque.
Minarik offers a wide variety of drives to properly control these machines, as well as motors to solve any motion control need.
Once you have selected a motor based on your performance needs located on pages 38-40, match the compatibility of your
motor with your Minarik drive on pages 41-44.
