7.Rated horsepower 额定功率:电机能做多大功取决于它,它的计算公式:Horsepower(hp)=[Motor Speed×Torque (lb-ft)]÷5,250 , 1hp=746w, 利用它我们可以计算额定电流以及选取供电系统的大小。 8.Duty 工作制: 一般motor这个参数是: CONT (continuous duty),电机在额定环境温度下,额定负载运行24/7, 即可以连...
Keyways follow standard ANSI dimensions listed in the chart at right. ???Torque Ratings- Couplings are rated by the maximum torque they can carry, and sometimes by a limiting or maximum rpm. Maximum torque can be used to determine horsepower (or vice versa) by the following formula: Coupling...
l. Motor horsepower and rpm. m. Voltage at each connection. n. Amperage for each phase. o. Full-load amperage and service factor. p. Seal type. 2. Test Data (Indicated and Actual Values): a. Static head in feet of head or psig. b. Pump shutoff pressure in feet of head or psig...
