When selecting motors, first decide voltage, frequency, number of poles, output power, frequency of use, and mounting method. In addition, it is necessary to decide ambient conditions, connection methods with load, and mechanical options. igure 1 oad factor and efficiency fficiency oad factor kw kw 0.75kW supply otors are designed to have their best performance when operating according to rated voltage and rated frequency displayed on the nameplates. To avoid using in different condition from nameplates leads to an effective energy saving. fficiency of motors fficiency of motors is ratio of output to input. When selecting motors, please carefully consider load factor, output power, and number of poles as mentioned below; 1. oad factor and efficiency s igure 1 shows, motors generally have maximum efficiency with 75%~100% of load factor. Thus, if the motors are operated in this range, it would save energy the most. If load factor is too low, motors may have to be reconsidered. 2. power and efficiency Precaution when using high efficiency motors s igure 1 indicates, efficiency of motors in rated load (100% of load factor) becomes higher as the motor capacity becomes large. owever, as mentioned above, efficiency is low when using motors in low load factor. It is necessary to consider the load carefully and decide the motor capacity. lso, to reduce power loss due to idle running of motors, it may need to stop operating the motors when they are not used. 3. otational speed and efficiency fficiency of motors generally depends also on the speed. If load is fixed, the number of poles and speed will be decided considering the usage of saving electricity, efficiency of deceleration devices, etc. lso, if motors need to operate in variable speed, VI SPD DIV is necessary to control operation for various load change. igh efficiency motors generally rotate faster than standard efficiency motors because of generated loss reduction. If standard efficiency motors are replaced by high efficiency motors in pump, fan, etc. applications, the rotational speed becomes faster and the output increases. lthough efficiency of motors is high, power consumption may increase with increased output power. lso, primary and secondary resistance may be decreased to reduce copper loss, which results in high starting compare to standard efficiency motors. In that case, breaker may have to be changed

16 Toshiba Variable Speed Drive series Plentiful variations, from simply adjustable speed control to vector control otes in case operating motors with variable speed drive (VSD) igh Performance characteristics otor end surge voltage suppression When a motor is driven by VSD, its operation is restricted by the VSDs overload rating, so the starting characteristic is different from those obtained from commercial power supply operation. lthough the starting is smaller with VSD than with the commercial power supply, a high starting can be produced at low speeds by adjusting the V/f pattern boost amount or by employing vector control. (It depends on motor specification and setting of VSD (maximum 200%)), When a larger starting is necessary, select VSD with a larger capacity and examine the possibility of increasing the motor capacity. oise In the system of operating 400V class high efficiency motor driven by the voltage type PW VSD using super highspeed switching device (e.g. IT), insulation degradation of motor wiring may occur by the cable length, cable installation method and the cable type. In this case, the following countermeasures are suggested. In case of normal insulation motor Suppress the surge voltage by reactors or surge suppression filter to keep surge voltage at motor terminal below 850V. In case of enhanced insulation type of motor Permissible surge voltage of motor is 1250V or less. When surge voltage is generated more than 1250V, suppress the surge voltage by reactors or surge suppression filter at load side of VSD. igh Performance Inverter V-S1 3-phase 200V kW 3-phase 400V kW ulti-function/ompact V-S15 3-phase 200V 0.215kW Single-phase 200V kW 3-phase 400V 0.415kW Dedicated to fan and pump V-PS1 3-phase 200V 0.490kW 3-phase 400V kW (1) The magnetic noise of motor with VSD drives is larger than operated by the commercial supply. oreover, when the motors are operated over rated speed, the windy noise of the motors increases. (2) To reduce noise, install noise reduction reactor between VSD and motor or use silent type VSD. Please contact us. Input voltage When input voltage becomes remarkably low due to vector control etc., consider using dedicated motor. In case the surge voltage becomes larger than permissive voltage, install reactors or surge suppression filter at load side of VSD.
