DC motors for the food industry

The BG65 motors from Dunkermotoren have smooth housings in order that machinery and facilities manufacturers working within the food and beverage industry are able to capitalise on the advantages of electronically commutated DC motors.

The smooth surfaces largely prevent the build-up of dust, dirt and residue from leakages. In addition, the blind bore and counter draft-free housing is simple to clean. These motors are thus suitable for application in the production of foodstuffs and drinks. They also have advantages in environments where a high degree of contamination occurs; for example, in the manufacture and processing of paper and cardboard, as well as in packaging machinery. Inadvertent warming of the DC motors is thus avoided.

A particular advantage of the electronically commutated, brushless DC motor is its maintenance-free and wear-free operation. The design of the BG65 SI incorporates integrated electronics for a 4-quadrant drive. Multiple digital and analog inputs permit the selection of different functions, such as starting and stopping the movement, rotation clockwise or counter-clockwise, and holding position with or without torque. Additionally, a signal is available at a number of outputs for the direction of rotation, 15 pulses per rotation as well as an alarm signal. The housings are rated to IP54 and, where required, up to IP65. Versions are available for a 24, 40 and 60 V supply voltage with power from 65 to 140 W and nominal torque from 20 to 40 Ncm.
