The Technologies Of TSL Vibration Motors

Sonic Vibration Motor

A toothbrush sonic vibration motor is a compact electric motor that creates vibrations to assist in cleaning teeth. It is commonly found in rechargeable electric toothbrushes and powered by a small battery. The motor typically vibrates at frequencies between 25,000 and 40,000 Hertz (cycles per second). This high-speed vibration creates a scrubbing action that helps remove plaque and food debris from the teeth and gums.

The motor is usually housed in the toothbrush handle and connects to the brush head via a shaft or similar mechanism. The vibrations aid in loosening plaque and food particles, making them easier to clean away. Additionally, the motor can stimulate the gums and improve circulation, supporting healthier gums.

ERM Vibration Motors

Eccentric Rotating Mass (ERM) motors are the original technology for generating vibrations. They are easy to use and come in various sizes, offering different vibration amplitudes and frequencies to suit various applications. These motors are found in products ranging from smartwatches to truck steering wheels.

ERM motors can be designed using several motor technologies, such as iron core, coreless, and brushless, available in both cylinder and coin shapes.

The advantages of ERM motors are their simplicity and ease of control, especially with DC motors. For longer lifespans, brushless motors are a good option.

However, a limitation is that the amplitude is geometrically linked to the frequency and speed, making it impossible to adjust them independently.

We offer these motors in three types: iron core for low cost, coreless for medium cost and performance, and brushless for the highest performance and durability.

 
 
 

Coreless Vibration Motor

The coreless DC motor differs from traditional iron core motors by lacking a magnetic core in the rotor. Its unique coreless rotor/stator design addresses the common issues found in conventional motors. The coreless cup motor features a cup-shaped coil made entirely of copper wire. This coil is connected to the main shaft via a commutator and connecting plate, forming the rotor. These components, typically made of plastic and epoxy, secure the wires and transmit torque.

The coil rotates within the air gap, driving the rotor. This design reduces energy loss from eddy currents in the core, decreases rotational inertia, and enhances torque and acceleration. Coreless DC motors are compact, efficient, and customizable, offering low inertia and high performance. They are widely used in applications such as toy cars, drones, electric toothbrushes, and medical devices.

coin vibration motor technology in china

Coin Vibration Motor

Our coin or pancake vibrating motors are Eccentric Rotating Mass (ERM) motors, similar to pager motors in terms of operation. They follow the same motor drive principles, including H-bridge circuitry for active braking.

Brushed coin vibration motors feature a flat PCB with a 3-pole commutation circuit placed around a central internal shaft. The rotor of the vibration motor consists of two “voice coils” and a small mass, integrated into a flat plastic disc with a central bearing, which sits on a shaft. Two brushes on the underside of the disc contact the PCB commutation pads to power the voice coils, generating a magnetic field.

This field interacts with the flux produced by a disc magnet attached to the motor chassis. The commutation circuit alternates the direction of the magnetic field in the voice coils, which interacts with the N-S pole pairs in the neodymium magnet. As a result, the disc rotates, and the off-centered eccentric mass creates vibrations.

Linear Resonant Actuator

A linear resonant actuator (LRA) is a vibrating motor that produces oscillating force along a single axis. LRAs respond more quickly than ERM coin motors. For example, an LRA takes only 50ms to reach the highest vibration level, while a coin motor takes between 100ms and 200ms. LRAs, particularly Z-axis vibrating motors, provide tactile feedback perpendicular to their surface, improving acceleration and feedback quality.

As a result, many high-end applications prefer LRAs. Unlike brushed motors, which wear down over time due to brushes, the LRA motor is brushless, using a voice coil to drive the mass, with only the spring being the movable part that can fail. LRA motors generally last over five times longer than traditional coin motors.

It is important to note that LRA motors operate on AC power, meaning users need to add IC drivers to the PCB board to activate them.

micro brushless coin motor1

Brushless Coin Motor

The key feature of a mini brushless motor is the absence of brushes, which eliminates brush wear. This contributes to the motor’s higher efficiency, longer lifespan, and quieter operation.

The coin brushless motor includes a stator assembly, rotor assembly, and upper and lower shells. The smallest coin brushless motor we currently offer has a diameter of just 5 mm, making it ideal for lightweight wearables like smart rings and thin watches. A brushless DC motor lasts 5 to 10 times longer than a typical coin vibrator. They are more expensive due to the embedded IC used to drive the motor.

Brushless coin motors operate on DC voltage. It is important to avoid driving them in reverse, as this can damage the driver IC. To connect the motor, the positive voltage should be attached to the red (+) lead, and the negative voltage to the black (-) lead.

Our motor designs incorporate a variety of bearings and lubricants, chosen based on the specific application environment. In larger vibration motors, the bearing typically experiences the most wear, primarily due to the centrifugal force generated by the rotation of the eccentric mass. We will provide recommendations to help avoid any issues with the application specifications.

Encapsulation

In certain applications, covering the rotating mass can be beneficial. Additionally, the motor can undergo an extra sealing process to offer enhanced protection against the penetration of fluids.

Applications Of Vibration Motors

Common uses of vibrating motors span a variety of industries, including automotive, consumer electronics, medical devices, and industrial equipment. These motors are often employed in applications such as haptic feedback systems, vibration testing, and product assembly processes, offering precise motion for specialized tasks.

Vibration alerts are used to capture a user’s attention through tactile feedback.

 In the smartphone industry, these motors are utilized for functions such as incoming call alerts and message notifications. Users can perceive the arrival of information through vibration, enhancing their experience. In wearable devices, precision vibration motors are used for health monitoring, such as activity reminders and heart rate alarms, helping users better manage their health.
