Expert tips for the safe and cost-effective purchase of used circular saw motors – including a checklist!
Which voltage (230V or 400V) is better for my used circular saw motor?
The choice depends on your existing electrical installation and the required cutting power . For cuts in hardwood over 5 cm thick, a 400V three-phase motor (e.g. with 4 kW) is often the better choice as it offers more power and stability. 230V motors are usually suitable for lighter applications up to approx. 2.2 kW.
How much kW power does a motor need for a circular saw?
The power requirement (typically 1.5 kW to 5.5 kW or more) depends on the maximum cutting depth and the hardness of the material to be processed. For many standard applications, a 2.2 kW motor (230V) may suffice, while professional users often prefer 4 kW, 5.5 kW, or stronger 400V motors .
What should I look out for regarding the speed of a used circular saw motor?
The typical speed for circular saw motors is around about 2800 RPM (2-pole). This speed is optimized for most wood cuts and affects the cut quality and speed. A significantly deviating speed can negatively affect the cutting result.
Are brake motors necessary for circular saws, even in used models?
Yes, for safety reasons , motors with a brake for circular saws are often recommended or even required, especially in commercial use. A functioning brake quickly stops the saw blade after switching off and minimizes the risk of accidents..
What risks are there when buying a used circular saw motor?
Main risks are unknown prior wear, lack of warranty, and potential hidden defects. A thorough inspection before purchase is essential. Pay attention to running noises, vibrations, and the overall condition. For demanding applications like continuous operation (S6) , a new motor from ATEK Drive Solutions is often the safer choice.
What does the operating mode S6 mean for circular saw motors?
The operating mode S6 means “uninterrupted periodic operation with load interruption”. This means the motor is designed for applications where it runs continuously, but the load (the sawing process) occurs periodically. This is typical for circular saws and ensures that the motor does not overheat and has a long service life.
When should I buy a new circular saw motor instead of a used one?
It is advisable to buy new if highest reliability, a warranty, specific protection classes (e.g. IP55), energy efficiency, or an exact design for your application (e.g. operating mode S6) are required. Although the acquisition costs are higher, long-term lower maintenance costs and higher productivity can justify the price difference. Can ATEK Drive Solutions GmbH offer suitable new motors as an alternative to used ones?
