      Motor drives – Compact power packages

      Ketterer motor drives consist of a 24 V DC motor and a worm gear. The motor drives the entire system. The worm gear is needed to convert the torque and speed of the motor according to your requirements. In combination with a spindle, linear motion is generated from the rotating motion of the DC motor. The movement is limited to the length of the spindle. The spindle can be connected in two ways. If the spindle is connected as a through-going spindle, the motor drive moves freely on the spindle axis. If the spindle is permanently attached, the motor drive is rigidly installed in the system. Thanks to their compact design and smooth operation, Ketterer motor drives can be used universally. Together with a Ketterer controller, motor drives can be used to put together complete drive systems that meet the most individual requirements.

    2. Motor Testing MCA&ESA

      Motor Testing MCA&ESA

      Motor Testing is carried out to monitor the state of the electrical machines, to determine their condition and to identify in advance possible faults that could lead to production stops. Motor Testing can also be carried out to check electric motors that have just been purchased or repaired, to check the quality of the product or the effectiveness of the work done. Motor Testing can also be used to optimise energy consumption, so as to always use perfectly tuned equipment, limiting electrical consumption. “Offline” analysis (MCA) The Offline type of analysis, i.e. MCA Motor Testing is carried out on a de-energised motor, first from the main switchboard and then, if we have any doubts, from the terminal board. For an even more accurate result, in case of suspected anomaly, we can redo the test by moving the rotor slightly by hand. “Online” analysis (ESA) The type of analysis Online, i.e. ESA Motor Testing is carried out on an energised motor, from the electrical panel. This allows us to detect other types of defects in motors and electronic components. The advantage of this method: you do not have to stop the motor and so we can also check the inverter and the most important mechanical components.

    3. Motoric linear slides

      Motoric linear slides

      The motoric linear slides from ERO-Führungen are divided into three groups: linear stages, miniature linear stages, and flat linear stages. Linear stages are based on mechanical linear slides and are therefore available in these types of bearings: cross rollers, needle rollers, coated guides, dovetail, and profile rail guides. The miniature linear stages are very compact and are available in 3 different versions (spindle-, toothed belt, and eccentric drive). The flat linear stage is very space saving because of spindle mounted at the side. And so, he has got a low height, even as cross table.

    4. MR – Monitoring relays

      MR – Monitoring relays

      The MRM series devices have been developed for the reliable monitoring of AC and DC signals in single-phase and three-phase electrical systems. • Monitoring of various electrical parameters: voltage, current, power (AC/DC), frequency, phase sequence or power factor cosϕ • Suitable for use in low-voltage and extra-low-voltage installations thanks to a wide measurement range • Wide range of monitoring functions: signals when values exceed or fall below the adjustable threshold value or window range • Power supply: DC 12–48 V or AC 110–240 V

    5. MRS13R – Overcurrent Protection Relay

      MRS13R – Overcurrent Protection Relay

      Overcurrent protection relays in combination with circuit breakers are used primarily when conventional safety solutions are not possible, such as in high-current and high-voltage systems or in railway technology. They prevent electrical devices and systems from being damaged or destroyed by the harmful effects of excessive current in the event of short circuits or overload conditions. In contrast to many other conventional overcurrent protection solutions, many parameters can be configured with the MRS13R. In conjunction with circuit breakers, currents in the kA range can be switched and, in comparison to fuses, the switching state of overcurrent protection relays is reversible when the cause of the fault has been eliminated.

    6. Multi Cable Entry MCE

      Multi Cable Entry MCE

      To date, the multiple-cable-entry solutions available on the market have proved unsatisfactory for many users. Either they do not achieve the required values in relation to sealing or strain relief, or their installation is time-consuming – a fact that quickly becomes apparent in the overall cost analysis. AGRO has been developing and manufacturing high-quality cable glands in accordance with EN 62444 for over 65 years. The know-how gained from this in relation to radial compression fabrication of sealing items is now being used for the fi rst time in cable feedthroughs. The specially-designed and reliable strain relief, together with the use of tested sealing units make MCE an innovative, extremely robust and dependable cable entry system. Summary of AGRO MCE’s advantages: • High tightness IP 68 • Absolute process reliability • Resists high pull-out forces according EN 62444 • Quick, economical installation • Extremely robust and versatile • No supplementary materials or lubricants required
