Electromechanical design and counterweight adjustment of YZU motors
Three-phase asynchronous vibratory drive motors Yangzhou JBM Vibration (JBM) YZU Series convert electrical energy into directional mechanical oscillating thrust by rotating adjustable eccentric counterweights mounted on both ends of the rotor shaft.
The centrifugal excitation force is tuned by altering the angular displacement between adjustable outer weights and fixed inner weights across an indexed circular dial.
When counterweight pairs are aligned in identical phase angles, the drive motor produces peak centrifugal excitation thrust required for heavy sizing screens and bulk material feeders.
Adjusting the angular offset decreases vibrational amplitude, moderating dynamic loads transferred into supporting machine frames and preventing structural metal fatigue during fine powder sorting operations.
Heavy-duty bearing assemblies and lubrication practices in JBM drives
Severe cyclical reversing dynamic loads demand heavy-duty spherical roller bearings engineered specifically for vibratory duties inside Yangzhou JBM Vibration drive motors.
An enlarged internal radial clearance C4 compensates for rotor shaft thermal expansion caused by continuous operation in hot industrial workshops. Precision bearing assemblies utilize massive machined brass cages that absorb shock loads without cracking.
Lubrication is maintained through high-temperature synthetic grease fortified with extreme-pressure anti-wear additives applied via grease nipples on motor end shields.
Regular replenishment at scheduled operating intervals prevents bearing raceway overheating, ensuring durable service life under sustained shaking.
Side-plate flange mounting engineering for YZU Type C vibratory motors
Vibratory motors Yangzhou JBM Vibration (JBM) Type C are mounted directly onto the structural side walls of vibrating screen boxes via a rigid lateral Side-Plate flange.
This arrangement eliminates external support beams and cantilever brackets, reducing total machine weight and simplifying layout within compact plant footprints.
When tightening high-tensile flange mounting bolts, torque verification with calibrated torque wrenches and the use of locking fasteners are mandatory.
Direct planar surface contact between machined joint faces distributes dynamic excitation moments smoothly across the side plate, preventing localized stress concentrations and sheet fatigue cracking.
Vertical vibratory motor dynamics for circular sizing separators
Vertical flange-mounted vibratory motors Yangzhou JBM Vibration (JBM) YZU Series Type L are specifically developed for circular sizing separators, scalpers, and vibratory finishing drums.
Separated upper and lower eccentric counterweights generate spatial three-dimensional elliptical wave motions across screen meshes.
Adjusting the spatial phase lead angle of the lower counterweight relative to the upper weight permits precise tuning of radial material travel speed from screen center to discharge periphery.
This tailored three-dimensional kinematic motion prevents wet fine particles from blinding screen openings, maximizing throughput per unit mesh area and providing steady self-cleaning action.
Construction of dust explosion-proof vibratory motors YZUB Series
For manufacturing plants handling combustible airborne powders, the joint venture Yangzhou JBM Vibration produces the YZUB explosion-proof vibratory motor series.
The heavy motor housing is formed from ductile alloy iron with external cooling fins and is sealed by elastomeric O-rings along all joint faces and counterweight covers.
Precision labyrinth shaft seals prevent combustible flour, coal dust, or chemical particulate matter from entering bearing chambers.
Stator windings are impregnated with high-strength thermoset resin, while embedded PTC thermal sensors continuously monitor internal temperatures, safeguarding against electrical faults and sudden downtime.
Dual motor self-synchronization on linear screens and feeders
On horizontal and inclined linear vibrating screens, conveyors, and heavy reclaim feeders, a dual-drive configuration with Yangzhou JBM Vibration (JBM) motors is frequently applied.
When two counter-rotating vibratory drive motors operate in parallel on a shared floating frame, dynamic self-synchronization occurs automatically.
Transverse centrifugal force vectors cancel each other out continuously, while longitudinal force vectors combine to produce straight-line oscillating thrust for the material trough.
Maintaining identical static moments on both counterweight sets ensures stable bulk material conveyance under optimal discharge angles without irregular rocking motions.
