Fig. The design for your drive is based on a few input parameters, such as mass, stroke/movement distance and cycle time. There are differences in characteristics between standard AC Motor Sizing Calculations This section describes certain items that must be calculated to find the optimum motor for a particular application. of all other motors supplied by the same feeder • No provision for going UP to next standard size must go down to next standard size NEC To size a motor for this kind of application, match the motor output rating to the load's torque converted to horsepower: where T = torque in lb-ft. 86) = 11. Oriental Motor recommends additional sizing be performed to confirm accuracy. STEP 1 : Calculate the power number of the STEP 4 Motor Sizing Support. GPM of Flow Needed for Fluid Motor Speed. Motor Sizing | ORIENTAL MOTOR U. 9k Note: It's recommended to check the ampacity of a wire after doing a voltage drop calculation. In both BS and IEC calculations, the KW calculation is based on a power factor of 0. Power factor is the ratio of true power (kW) to Which do you use — full-load current (FLC) or full-load amperes (FLA) — for your motor calculations? Fig. It is also the reciprocal of the motor’s thermal resistance, T R, usually given in deg C/Watt. Viscosity. 4. The free-of-charge motor sizing STEP 2. Open simulation tool. To determine the appropriate fuse size for a motor, you should first identify the motor’s full load current (FLA) from its nameplate or specifications. 62 Feeder O. Perform feeder conductor size calculations the same way as for branch 3-Phase Motor Amperage Calculator .
