A family of drives: ELECTROMEN EM-241 for DC Motor Control

Listen to this article

When you have a motor requirement, it is often common to focus on the motor alone and fail to consider the part played by the drive. However, drives are vital components. Drives can enhance and improve your motors system by enabling additions to straightforward motion control.

If you are looking to control DC brushed motors, the Electromen EM-241 range will likely have a product that will provide an excellent fit for you. These programmable drives have options for closed loop feedback to provide accurate control of your speed or position preferences. The EM-241 drive range has been developed to work with brushed DC motors in a wide range of applications where special functions are needed.

So, let's look into the EM-241 family of motor drives…

About Electromen

Electromen are a power electronics company, specialising in motor control products. They are based in Tuku, Finland and have been designing and manufacturing customised control and electronic measurement products since 1988.

Their core range includes drives for brushed DC and brushless DC motors, stepper motors, DC linear actuators, and the list can go on…

Applications vary widely and include – agricultural machinery; access control; door and canopy automation; lifts, material handling and essentially anything that requires brushed DC motor control.

Why would you use this drive?

Several important reasons could lead you to this answer. Electromen programmable drives offer a broad scope of adjustments with the stock firmware.

Let's look into some of the main points:

Control

Control is the most common use for a motor drive – drives control speed and direction with voltage and polarity, and of course torque, with current control. The drive can provide discrete or continuous control with adjustable end limits and start/stop ramps to ensure smooth motion and reduced mechanical stress.

Depending on the model, they can provide positional control using hall sensor pulses or potentiometer feedback. Fault output behaviour can also be adjusted to provide feedback to the rest of the system and RS485 mod bus communication is also an option on some units.

Safety & Motor Protection

Safety is always a crucial design consideration and using a drive protects the motor windings from burnout. More importantly, it can also protect the end-user of the finished product by preventing trap points or dangerous running conditions. The mechanism of the drive can be set to stop or auto-reverse on stop when the over-current limit is reached.

Take a look at the Electromen EM-241 Family
