DC Motors and RPM Explained ben lee
DC Motors and RPM Explained

A question we are commonly asked here at Hydraproducts relates to DC motors and the typical RPM these units normally run at. The answer to this question is simple, and heavily dependent on the load applied to the motor.


A good starting point is to look at how much pressure the system requires. This is often the least flexible parameter, as it will determine such things as the amount of load that can be lifted. 


The flow rate is the next process that should be taken into account. This determines the speed of an operation and is typically more flexible.

With knowledge of these two factors, DC motor characteristic curves can then be used to determine which motor and pump combination best suits the application. To help you understand these curves and how to interpret them correctly, please refer to our previous blog on DC curves here.

The other important criteria on the curves is the duty cycle, S2 rating. This is a function largely determined by the current draw (Amps) and the physical ability for the motor to dissipate heat. So, the larger the motor size, the more easily it will radiate heat and the longer the S2 rating could be. 


Whilst this seems a long answer to a simple question it is the only full explanation to what is the rpm of the DC motor. 


Hydraproducts hosts a user-friendly product configurator which helps to tackle this process effectively. The user can spec their motor with options ranging from 500Watt to 3kW with motors over 1800Watt coming complete with thermal overload to help limit brush temperature inside the unit. Pumps and other accessories can then be added to the unit all the while the configurator works to ensure that all components are compatible with one another.


To see the Hydraproducts configurator in action or to simply learn more about how it works and try out different custom fitments, please click this link which will take you directly to the configurator itself.
