Below you can find answers to questions frequently asked to Rotero. Feel free to contact us if you cannot find your question in the list. 

  • General
    • Can I go to Rotero as a private customer?

      Rotero is an industrial supplier and we focus primarily on machine manufacturers with serial needs. We do not supply separate parts to private customers.

    • What is the delivery period when Rotero does not have a product in stock?

      If Rotero does not have a product in stock we will order it for you from our supplier directly after your order has been received by us. Since our partners are spread worldwide the supply period may vary. To assume a period of 4 to 6 weeks will in most cases be about right. We indicate an expected delivery date on the order confirmation so that you know what you should expect. 

    • For what applications can Rotero products be used?

      Rotero products can be applied in various industries. We are focus primarily on machine manufacturers in the following sectors: food industry, agriculture and forestry, packaging machines and the medical industry. See also: applications

  • Technical
    • How does a stepper motor work?

      Stepper motors are used in particular for positioning applications. The angular warp is determined by the powered coil and the steering knows by counting where the motor is positioned. The frequency with which a subsequent coil is powered determines the speed. The electric current determines the power of the stepper motor but does not influence speed and position.

    • What is the lifespan of the carbon brushes in a DC motor?

      The lifespan of the carbon brushes is dependent on the construction of the commutator and the quality of the brushes. While “low cost” motors last usually only 500 to 1,000 hours, the lifespan of the better (more expensive) DC motors is between 2,000 and 5,000 hours. Pancake motors, where the brushes run smoothly over the coils, can last for 15,000 hours. 

    • What type of motor can be controlled from a speed of 0 to ... rpm?

      Practically every type of motor is characterised by “irregular running” at low running speeds. Depending on the type of motor and whether an encoder is used, the lower limit lies at about 50 to 200 rpm. The only type of motor that can be regulated from 0 rpm is a stepper motor. A good driver with microstepping mode is needed to achieve this because the motor vibrates excessively (due to “aggressive” stepping of the motor).
