Parameter explanation Nominal values Nominal value Value of a variable (e.g. voltage, current, resistance ...) according to which a motor, blower, or pump, or its characteristics and parts are specified or according to which they are designated. Power consumption P1 Example Theoretically, a nominal voltage of 24 V and a rated current of 35 A result in a power input of P1: P1 = UN · IN; P1 = 24 V · 35 A; P1 = 840 W. This power consumption P1 and the output P2N (see Fig. page 7) determined from the characteristic-curves chart are used to calculate the efficiency η: P1 = U · I P1 Power...

Code letters If an index number is not given, then the letter “X” must be substituted (i.e. “XX”, if both index numbers are missing). Additional and/or supplementary letters can be omitted without any substitution: 2) T he supplementary letter “K” is placed either immediately after the first index numbers 5 and 6 or immediately after the second index numbers 4, 6 and 9. 3) D uring the water test for example: IP16KB protection against ingress of solid foreign bodies with a diameter ≥ 50 mm, protection against powerful spray water at high pressure, protection against being touched by fingers....

Operating modes Continuous operation S 1 Operation with constant load condition, the duration of which is sufficient to reach the thermal steady-state condition. Parameters for curve inspection P1 Power input PV Power loss Temperature max Highest temperature Load period tB Relative on period (as percentage) tr tS Duration tSt Standstill period Short-term operation S 2 Operation with constant load condition, which does not last long enough however to enable the thermal steady-state condition to be reached, and a subsequent pause, which lasts long enough for the motor temperature not to...

Characteristic curves With a specified working point of 160 Ncm one plots a vertical line to the torque axis. The intersecting points of these vertical lines with the various characteristic curves result in the operating data for the rated speed nN, rated current IN and mechanical output P2N. Explanation of characteristic curve evaluation AP Working point M Torque P2 Power output I Current n Rotational speed Example: Given: MN = 160 Ncm Found: nN = 3.800 rpn (min–1) P2N = 636 W and IN = 35 A Bosch Automotive Aftermar

Motors with Hall sensor Hall effect Hall effect d Thickness of chip Characteristic curves If a current IS flows through a chip, a Hall voltage UH is generated transverse to the direction of the current, the size of which is proportional to the magnetic induction B (vertical to IS) and the current IS. The Hall voltage UH is made up of: RH Hall-constant factor Since the resulting Hall voltages are extremely small, they are amplified. When using silicon Hall elements, the circuit for signal processing (e.g. a Schmitt trigger with subsequent driver) are integrated directly onto the same chip....
