Watt Drive is anxious to achieve highest modularity in its products. Through close cooperation of the development teams, a new system motor will be created that unites the high WEG quality requirements with the unique modular system of Watt Drive. The new motor generation can be offered as minimum efficiency class IE2 as well as IE3 and it can be combined with efficient Watt gears and thus be designed as an energy saving and environment-sparing drive system.
The completion of the new product lines is planned in the 1. quarter 2013.
Features:
The EUSAS® motor (Europe - USA - ASia)
The strong points of the new modular motor are not only preserved but also enhanced. With the specialised 12-strand design of the motors, high voltage flexibility can be achieved by switching to up to four different voltage levels (Y/D, YY/DD). Additionally an enhanced frequency inverter operation (100Hz, 120 Hz, constant torque) can be realised. With frequency inverster operation, the rated motor power even doubles. Furthermore through the patented WISE® isolation system of WEG motors the durability of the stators is increased as well, when operating with frequency inverters.
Modular System
The motors have been especially designed for the assembly of various motor modules so that the flexibility rises and a quick delivery is guaranteed. On customers’ requirement the motor modules can be mounted singly or in combination.
Some of the most important mechanical motor mountings:
Picture 1: Self ventilated modular motor with spring-loaded brake, manual release and incremental encoder
Spring loaded brake
Robust rectifier spring loaded brakes with 24 VDC, 230 VAC or 400 VAC ensure the proper brake power.
Optionally obtainable:
Encoder systems
Various encoders can be mounted within or outside the fan cover.

Forced cooling
The ventilation is obtainable as single-phase, three-phase and with wide voltage range.

Backstop
The very robust built backstops prevent e.g. return movement of the conveyor material on upward conveying machinery.

Alternative connection technique:
The MIP box can be equipped with up to 22 terminals and one brake rectifier. All options of the Watt motor system like brake, encoder system etc. can be realised in only one terminal box.

Advantages:
The MultI pluG (MIG) connect is a decentral standardised connection variant that Watt Drive uses for the integration of power- and operation wiring of motor modules in just one plug.
