Electric vibration motors ERA

Electric vibration motors ERA (three-phase unbalance motor) are available in many different sizes and power ratings. These vibrators feature long life as well as rugged construction, making them best suited for continuous use.

This type of vibrator motor can be supplied for two different rated speeds (3000 & 1500 rpm).

Our Electric Vibration Motors ERA are suitable for a very wide range of applications and many standard applications, such as mounting on silos, hoppers, feeders and screens. Here, depending on the application and design, it can be used for compacting, loosening and conveying bulk materials.

Vibration

Compared to a “normal” electric motor, the vibration motor has an extended shaft on both sides. Eccentrically mounted weights are located on this motor shaft. When the motor shaft rotates, the unbalanced weights generate a circular oscillation (the vibration).

The bearing of the motor shaft consists of generously dimensioned bearings suitable for continuous use in order to withstand this overload permanently.

Electrical connection

All vibrators are suitable for operation on a mains supply with a frequency of 50 Hz or 60 Hz and generate a circular vibration. They have multi-pole stators and are available in the following graduated standard speeds:

3000 rpm (2 pole)
1500 rpm (4 pole)

By using a frequency converter, the speed of the vibrator can be continuously adjusted. Thus, different vibration frequencies can be realized in order to optimally adapt the motor to an existing task.

Voltage: three-phase 380/400 volts (star connection) or 230 volts (delta connection)

Adjustment/adaptation

The unbalance force and vibration amplitude of the vibrator can be adjusted by means of adjustable unbalance weights mounted in pairs on the shaft ends.

Protection/Safety

ERA series vibratory motors are protected to IP66 against the ingress of water and foreign bodies and can be used at temperatures from -20°C to +40°C.

CE conformity

The vibrators of the standard series have an explosion protection certification according to ATEX category: II 2D (zone 21, 22), degree of protection: tD A21 IP66.

For higher protection classes a separate series is available, with certification category: II 2 GD, protection degree: Ex e IIC T3/T4 Gb Ex tb IIIC T…°C Db.

Also available is a version in full stainless steel, particularly suitable for the pharmaceutical and food processing industries. Please contact us!

Spare parts/repairs

We also carry out overhauls and repairs of defective unbalance motors. This includes, among other things, the re-bearing of the rotor and replacement of defective components. Please contact us in advance for this.
