Overview

This document provides detailed technical specifications and dimensional data for the TG Series three-phase asynchronous motors. It includes motor frame sizes, mounting types, shaft dimensions, and comprehensive performance data across various power ratings and speeds.

1. Motor Dimensions and Mounting

The document lists overall and installation dimensions for different motor frames, including foot mounting (B3), flange mounting (B5), and general mounting types. Key parameters include shaft diameter, length, and mounting hole dimensions. Frame sizes range from 80 to 355, with corresponding shaft diameters from 22 mm up to 100 mm. Dimensional tolerances are specified (e.g., l10 ±0.5 mm).

2. Motor Technical Data

The technical data section tabulates motor models with the following parameters:

• Power (kW): Ranges from 0.37 kW to 315 kW.
• Speed (r/min): Various speeds including 3000, 1500, 1000, 750, and 600 rpm, corresponding to different pole counts.
• Current at 380 V (A): Nominal current values for each motor model.
• Efficiency (%): Efficiency values range from 62% for the smallest motors to over 95% for larger models.
• Power Factor (cos φ): Typically between 0.6 and 0.93, improving with motor size.
• Torque Ratios (Tmin/Tn, Tmax/Tn): Starting and maximum torque relative to nominal torque, generally between 1.9 and 3.3 times.
• Starting Current Ratio (Ist/In): Starting current relative to nominal current, ranging from 3 to 7.5 times.
• Weight (kg): Motor weights vary from approximately 15.5 kg for small motors to 1850 kg for the largest models.

3. Motor Series and Pole Configurations

The TG series motors are available with 2, 4, 6, 8, and 10 poles, affecting speed and torque characteristics. Each pole configuration has a dedicated table listing models with corresponding performance data.

4. Key Performance Highlights

• Efficiency improves with motor size and power rating, reaching up to 95.2% for the largest 3000 rpm motors.
• Power factor generally increases with motor size, indicating better electrical performance.
• Starting torque and current ratios are designed to ensure reliable motor startup under load.
• Weight increases significantly with motor size, important for installation and handling considerations.
