Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.

    V-Belts will transmit power satisfactorily over a wide range of tensions. An experienced user can develop a "feel" when a drive is tensioned within this range. However, in order to optimize belt life and performance and to avoid undue stress on shafts and bearings it is desirable to calculate and measure belt tension based on drive loads.

    The service factor - SF - is a measure of periodically overload capacity at which a motor can operate without damage. The NEMA (National Electrical Manufacturers Association) standard service factor for totally enclosed motors is 1.0.. A motor operating continuously at a service factor greater than 1 will have a reduced life expectancy compared to operating at at its rated nameplate horsepower.

    Utilization factor - WikipediaDeze pagina vertalen

    In electrical engineering, utilization factor,, is the ratio of the maximum load which could be drawn to the rated capacity of the system. This is closely related to the concept of Load factor . The Load factor is the ratio of the load that a piece of equipment actually draws (time averaged) when it is in operation to the load it could draw (which we call full load).
