T/CECA-G 0009-2016 YSZL Series Self-exciting Three-phase Synchronous Motor Technical Specification (Frame Size 80-355)

Scope

This standard specifies the types, basic parameters and dimensions, technical requirements, inspection rules, marking, packaging, and warranty period of the YSZL series self-excited three-phase asynchronous motors (hereinafter referred to as "motors"). This standard applies to YSZL series self-excited three-phase asynchronous motors with frame sizes from 80 to 355, rated voltages up to 660V, rated frequencies of 50Hz, rated powers from 0.75kW to 375kW, and general-purpose motors operating under duty cycles S1 to S6. 4.1 Motor Model The model of a self-excited three-phase asynchronous motor consists of four parts: the product code, the specification code, the number of poles, and the power. The following is an example. Model example: YS Z L 132S 4 5.5 4.2 The enclosure protection grade of the motor is IP54. 4.3 The cooling method of the motor shall comply with IC411 as specified in GB/T 1993. 4.4 The structure and installation type of the motor shall comply with the provisions of GB/T997. 4.5 The duty cycle of the motor is applicable to S1 to S6. 4.6 The wiring method is Y/. 4.7 The correspondence between the frame size of the motor and the speed and power is specified in Table 1.
