1、Teco gear reducer motor is produced according to IEC60034-30, in IE3 and IE4 high efficiency level to save power. It is available for us to supply all reducer at various frequency and voltage per requirement. 

2、Teco gear motor adopts the common standard of motor industry. The outline dimension is compatible with most of gear motors manufactured by German company, in good versatility and easy in mounting. 

3、Our parts have compact structure, high impact resistance, stable running stable and low noise, long  ifetime, high reliability. 

4、The mounting methods as: vertical, horizontal, direct connected to motor and etc, which is in diversity and more flexible for customer’s selection. 

5、The gearbox is made from casting iron , with greater wear resistance, casting and machinability. 

6、Gear is produced from high quality low carbon alloy steel, with excellent performance in impact resistance, wear resistance and toughness. 

7、BS helical-worm gear units are more efficient than normal helical-worm gear units. 

8、High permitted overhung loads 

9、IP55 protection, with strong and safety iron casting frame. 

10、TECO Class F insulation, heat-resisting, resistance to electrical sparks, long insulation life, suitable for bad environment. 

11、Bearing and silicon steel sheet from famous brand company. Standardized design, high quality material,advanced processing equipment and perfect .quality system, all of them ensure motor in high efficiency, low vibration and reliable safety. 

Option: thermal protector , PTC, heater,RTD,PT100 etc.
