T/CECA-G 0017-2018 TEJ Series Crossover Variable Frequency Drive Permanent Magnet Synchronous Motor Technical Specification

Scope

Scope: This standard specifies the models, basic parameters, dimensions, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, and warranty period requirements of the TEJ series overlapping frequency-driven permanent magnet synchronous high-efficiency motors (hereinafter referred to as motors). This standard applies to 0.55kW to 1.5kW frequency-driven speed-regulated permanent magnet synchronous motors. All series of motors derived from this series can also refer to and implement this standard. Main technical content: 5.1 The motors shall comply with the requirements of this standard and be manufactured according to the drawings and technical documents approved by the prescribed procedures. For requirements not specified in this standard, they shall comply with the provisions of GB 755. 5.2 Under the following conditions, the motors shall be able to operate at rated conditions. If the on-site operating environment conditions deviate from the following, they shall be corrected in accordance with GB 755. 5.3 The deviation of the power supply voltage and frequency from the rated value during the operation of the motor shall comply with the provisions of GB 755. 5.4 Under the rated voltage and rated synchronous speed of 3000r/min, the guaranteed value of the loss-of-step torque of the motor relative to the rated torque shall comply with the provisions of Table 4. The motor shall be able to ensure constant power or constant torque operation within the speed range. 5.5 Under the rated voltage and rated synchronous speed of 3000r/min, the rated output power, rated current (before the controller), and efficiency (excluding the controller) of the motor shall comply with the provisions of Table 5. For motors without rated output power values listed in the table, the efficiency shall be determined by the linear interpolation method. 5.6 The motor is assembled by testing fixtures with the stator and rotor.
