Electric vibrators

Electric vibration motors ERM (Micro)

Electric vibration motors ERM (Micro) are the compact version of the vibration motors ERA. The ERM (Micro) is available in single or three-phase versions for 230 V / 400 V / 50 Hz. These vibrators are suitable for applications with limited installation space and those where light vibrations are required.

The particularly compact ERM (Micro) electric vibrators are ideal for mounting on small hoppers and storage bins of pellet heating systems.

Structure

Highly resistant aluminum light alloy, surface polished

Vibration

Vibration is generated by weights mounted eccentrically on the motor shaft. When the motor shaft rotates, these generate a circular vibration. The bearing of the motor shaft consists of generously dimensioned bearings suitable for continuous operation.

Electrical connection

All vibrators are suitable for operation on a mains supply with a frequency of 50 Hz and generate a circular vibration. They have two-pole stators and are available for standard speed 3000 rpm (2-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.

Connected loads: three-phase current 380/400 volts 50 Hz. The vibrators of sizes ERM Micro 4-3, 20-3 and 45-3 are also available in a single-phase version for operation on a 230 V AC connection.

Setting/Adjustment

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

Our ERM Micro series vibrators 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 3D, protection degree: Ex tc IIIC T100°C Dc IP65 (zone 22).

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.
