Electric vibration motors ERDC

The ERDC is a special version of the ERA unbalance motors for applications where DC and low voltage operation is required.

These external vibrators are used to support material flow, screening, compacting, sorting, loosening, conveying and cleaning by means of vibration. There are versatile application possibilities for all tasks in the field of bulk material handling. Due to the operation with direct current and low voltage, these vibrators are particularly suitable for mobile use, for example on construction site and silo vehicles.

Design

Highly resistant cast aluminum alloy

Vibration

Vibration is generated by weights mounted eccentrically on the motor shaft. When the motor shaft rotates, these generate a circular vibration.

The motor shaft bearing consists of generously dimensioned bearings suitable for continuous operation.

Electrical connection

Voltage: 12 VDC or 24 VDC (depending on version)

Standard speed: 3120 rpm (nominal speed)

By adjusting the armature voltage, the speed of the vibrator can be continuously adjusted. Thus, different vibration frequencies can be realized to optimally adapt the motor to an existing task.

Adjustment/adaptation

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

The two versions of the unit have an unbalance of 50 kg and 200 kg and a maximum centrifugal force of 490 N and 1960 N, respectively.

Protection/Safety

CE conformity

Mechanical protection class IP66 and suitable for an ambient temperature of -20°C to +40°C

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.
