One of the major benefits of a PMDC Motor has to do with the ability to adjust the speed. This is accomplished by simply varying the voltage applied to the armature. By integrating a feedback device within the system you can manipulate, maintain or verify speed. One application where this would be extremely beneficial would be in a pump system.
When a control is used in conjunction with a flow-monitor, a PMDC motor can be used to control the flow rate by controlling the motor speed. With a pump that requires a specific flow, a PMDC motor can be adjusted to ensure the proper speed is achieved.
