DC Motor Range Is Flexible And Adaptable
View Supplier's Number  |
Date Added: 4th May 2012
The DC motor range from maxon motor offers many outstanding technical features. With no magnetic cogging, high acceleration thanks to a low mass inertia, low electromagnetic interference and low inductance, they are highly efficient. They have linearity between voltage and speed, load and speed, and load and current and small torque ripple thanks to the multi-segment commutator.
They are able to bear high overloads for short periods and the compact design and multiple combination possibilities with gears as well as DC tachometers and encoders, the DC motors are flexible and adaptable.
Benefits of maxon's DC motor
At the heart of the maxon motor range is the worldwide patented ironless winding, System maxon. This motor principle has several very specific and impressive advantages. It ensures no magnetic detent and minimal electromagnetic interference and also gives efficiency of up to 90 per cent - far exceeding other motor systems.
Each type of DC motor has numerous winding variants, differentiated by the wire diameter and number of turns. Wire sizes used are between 32 μm and 0.45 mm, which gives different terminal resistances and influences the motor parameters that describe the transformation of electrical and mechanical energy (torque and speed constants). This means users can select the DC motor that is best suited to their requirements.
The maximum permissible winding temperature is 125 degrees C, but can be as much as 155 degrees C in special cases, meaning the motors are usable in even the most intense environments.
Turning speed
The DC motors have an optimal operating speed between 4,000 rpm and 9,000 rpm depending on the size. Specially adapted versions can meet speeds of up to 20,000 rpm.
One of the physical properties of the DC motor means that, at a constant voltage, the speed is reduced with increasing loads. Adaptation to desired conditions is possible due to the variety of winding variants. At lower speeds, a gear combination is usually a better option than a slowly turning motor.
Service life
Many factors influence the service life of DC motors, but all maxon motor products are robust and built to last. Service life can vary between more than 20,000 hours in favourable conditions, to under 100 hours in extreme, intense use. On average, around 1,000 to 3,000 hours of use can be obtained.
Things that influence service life include; the electric load, as higher current loads result in greater electric wear; speed, as higher speeds lead to more mechanical wear; type of operation and environmental influences such as temperature, humidity and vibration.
