Our micro vibration motors are designed to initiate starting torque as low as 0.8V DC. This low current-spike startup safeguards complex driver boards from thermal strain and extends battery life in modern IoT nodes.
By leveraging high-density tungsten alloys instead of common brass weights, our custom designs generate up to 45% greater G-Force amplitude without modifying the overall micro frame size.
For applications exposing components to biological fluids or corrosive elements, we construct fully enclosed, IP67+ hermetically sealed micro capsules that shield the coreless rotor structure.

Our manufacturing complex represents the peak of Chinese supply chain optimization, housing high-precision machinery and rigorous testing apparatus.
Operating out of the heart of China's advanced hardware cluster in Guangdong, WICCA Motor provides a vertical manufacturing pipeline. We secure raw commodities (such as high-coercivity NdFeB magnets and high-purity oxygen-free copper coils) with direct factory agreements, insulating our clients from international supply chain disruptions.
By consolidating precision CNC machining, mold manufacturing, and testing within one campus, we shorten prototyping loops to under 7 working days. Our automatic winding, lathing, and gear-hobbing fleets scale easily from high-mix, low-volume test runs to million-unit mass production, offering predictable turnaround times and consistent unit pricing.
Guarantees strict tolerance control down to ±0.005mm.
All components conform to REACH, RoHS, and CE guidelines.
Rigorous, documented QA/QC audits at every station.
How global system developers integrate WICCA's micro vibrating motors to achieve functional goals across diverse industries.
We supply high-torque, durable DC vibration motors integrated into driver steering wheels, lane departure warning systems, and ventilated smart seats, offering immediate tactile feedback with silent operation.
For drug delivery systems, personal insulin pumps, and physical therapy equipment, our coreless N20 and carbon brush 050 variants provide localized physical feedback and fluid-mixing capabilities with high reliability.
Biometric door locks and smart safes leverage our low-power 1.5V and 3V micro drive motors for lock bolt engagement, where miniature profiles and low standby current consumption are critical.
From skin scrubbers and micro-massagers to adult novelty items, our flat coreless vibration motors and hollow-cup assemblies deliver stable high frequencies (up to 12,000 RPM) while remaining compact and waterproof.
Low-voltage (1.5V to 3.7V) cylindrical micromotors provide tactile responses in interactive toys, controllers, and wearable IoT monitors without quickly draining small lithium batteries.
Used to power structural micro-vibrations in specialized CD/DVD/VCR player assemblies, bell mixers, and precision fragrance dispensers requiring continuous, reliable motor operation.
Our commitment to R&D ensures we stay ahead of industry trends, paving the way for smaller, smarter haptic components.
As micro-electronics shrink, the demand for smaller actuators grows. Our engineering roadmap focuses on reducing diameter tolerances to under Ø3mm while maintaining adequate mechanical torque.
By designing integrated sensor coils into the motor backplate, we aim to enable closed-loop feedback systems. This allows real-time diagnostics of the eccentric load, helping designers adjust the drive pulse based on changing mechanical resistance.

Common technical questions from project leads, hardware engineers, and procurement teams answered by WICCA Motor's technical department.
Eccentric Rotating Mass (ERM) motors use an asymmetrical weight attached to the shaft of a DC motor. Applying a DC voltage spins the weight, creating centrifugal force that vibrates the entire unit. Changing the voltage changes both speed and amplitude. Linear Resonant Actuators (LRAs) use an AC signal driven through a voice coil to move a suspended mass back and forth in a linear path, vibrating only at a specific resonance frequency. LRAs offer faster response times and longer life, but require a dedicated external driver IC.
The startup voltage is the minimum voltage required to overcome static friction (stiction) and begin spinning the eccentric weight. In battery-powered devices, this starting voltage must be kept low. If a motor needs a high voltage spike to start, it can cause voltage drops across the system bus. Our motors are engineered to start reliably at 0.8V to 1.5V DC, ensuring stable performance even as the battery drains.
Vibration motors generate acoustic noise, which can be undesirable in devices like high-end beauty tools or medical wearables. We minimize this by using high-precision internal bearings, dynamically balancing the rotor, and housing assemblies in sound-dampening structures. Testing is done in our anechoic chambers to keep sound levels below 35 dB(A) under rated loads.
Precious metal brushes (usually containing gold, silver, or platinum alloys) are ideal for low-voltage, low-current applications like smartphones or small wearables. They have lower contact resistance and startup voltages, but can wear out faster under heavy loads. Carbon brushes are better for heavy-duty, high-voltage industrial uses (like tools or automotive seats), as they handle electrical arcs better and offer longer lifespans under continuous load.
Yes. We offer fully customized leads, including custom wire lengths, JST or Molex connectors, and flexible PCB terminations. We can also mount the motors directly into rubber boots or custom plastic brackets, helping to absorb unwanted vibration and simplify installation on your assembly line.
