  • Page 26: Options And Accessories

    Options and accessories Options and accessories Asynchronous drum motors with frequency inverters 6.1.1 Torque depends on input frequency Operating frequency [Hz] 30-50 Available motor torque in % Rated motor 50 Hz frequency 60 Hz Value 1: Based on a rated motor frequency of 50 Hz (50-Hz motors should be operated only up to 70 Hz in the speed range under field control.) Value 2: Based on a rated motor frequency of 60 Hz (60-Hz motors should be operated only up to 80 Hz in the speed range under field control.) The torque dependency depicted in the figure above is expressed as P = T x ω. With a reduced operating frequency of below 20/24 Hz, the motor torque is reduced by changing heat dissipation conditions. The power loss dissipation is a result of the oil quantity, in contrast to standard ventilated motors. For frequencies starting at 80 ... 85 / 95 100 Hz, the curve for the output torque does not have a hyperbolic shape, but is instead replaced with a quadratic function...
  • Page 27 However, since all Interroll drum motors run in an oil bath, the risk of overheating or damage to the motor due to high voltage increase rates is extremely low.

Install the brackets at the conveyor or machine frame. Ensure that the drum motor is installed parallel to the idler pulley and at a right angle to the conveyor frame.
  • Page 32 Assembly and installation Axial clearance The entire axial clearance of the drum motor should be at least 1 mm (0.5 mm per side) and no more than 2 mm (1 mm per side). Torsional clearance for standard applications (left) and for applications with frequent reversing duty or start/stop operation (right) If necessary, install a support plate above the mounting bracket to secure the drum motor shaft.

  • Page 33: Belt Assembly

    Ensure that the drum motor is operated with a conveyor belt that covers at least 70 % of the drum tube. ¾ For drum motors with less than 70 % belt contact and drum motors with form-fit driven belts or without belt, the required output should be multiplied by 1.2. This must be specified at the time of ordering. If in doubt, please contact Interroll. 8.3.1 Belt adjustment Convex tubes center and guide the belt during regular operation. Nevertheless, the belt should be carefully aligned, frequently checked during startup and readjusted depending on the load.

  • Page 34: Tensioning The Belt

    Tensioning the belt The required belt tension depends on the respective application. The pertinent information is located in the catalog of the belt manufacturer, or contact Interroll.

  • Page 39: Electrical Connection Of The Drum Motor

    The protective device must be adjusted to the rated current of the corresponding motor (see type plate). Interroll synchronous motors may be operated only with frequency inverters that feature a control suitable for permanent magnet synchronous motors (PMSM).

  • Page 40: Integrated Thermal Protection

    For operational safety, the motor must be safeguarded against overload with an external motor protection, as well as an integrated thermal protection; otherwise, there is no warranty if the motor fails. 8.8.6 Frequency inverter Asynchronous drum motors can be operated with frequency inverters. Frequency inverters from Interroll are general adjusted to factory setting and have to be parameterized for the respective drum motor. For this purpose, Interroll can supply parameterization instructions. In this case, please contact your local Interroll partner. • If no frequency inverter from Interroll is used, the frequency inverter must be correctly parameterized according to the specified motor data. Interroll can provide only very limited support for frequency inverters that are not being...

  • Page 42: Initial Startup And Operation

    Ensure that no contact points exist between objects, conveyor belts and rotating or moving parts. Ensure that the drum motor and the conveyor belt can move freely. Ensure that the belt features the correct tension according to the recommendations from Interroll. Ensure that all bolts are tightened according to the specifications.
