ABB has upgraded its range of low voltage flameproof motors with new products in IEC frame sizes 80 – 132. The new motors have been designed to provide greater versatility through easier installation and modification.
ABB manufactures a full range of EEx d and EEx de flameproof motors, covering IEC frame sizes 80 – 710 and power ratings of 0.55 – 4500 kW, low and high voltage.
The new products represent the smaller-size end of the low voltage EEx d and EEx de range, frame sizes 80 – 132 and ratings of 0.55 – 7.5 kW. The new motors are supplied with loose feet as well as flange rings rather than flanges – design features that make installation and modification easier.
A 4 x 90° turnable terminal box is fitted as standard, the same box being used for all shaft heights. The EEx de motors are fitted with a siliminium cable flange and EEx e approved cable glands as standard.
The new motors feature higher efficiency and lower temperature rise than previous versions and 3 x 150°C PTC thermistors are included. 2-pack epoxy paint is used, as in the motors for IEC frame sizes 160- 400.
