The precise, human-like movements required for a robot hand are made possible by installing a micromotor at each joint.

As robot hands become more complex with multiple fingers and joints, the torque requirements increase. This is why small, lightweight motors with high torque are gaining attention. By utilizing compact, high-output motors, the robot hand’s performance is enhanced, making it capable of handling heavier objects and more demanding tasks.

Other applications for micromotors in the laboratory

In addition to the equipment mentioned above, micromotors play an important role in many other laboratory devices. Here are a few more examples of their applications:

Centrifuge

A centrifuge is a device that separates components in a sample by spinning them rapidly. Micromotors are used for driving the rotor. Centrifuges spin very fast and require compact yet high-output motors.

Micromotors are capable of smooth acceleration and deceleration, precisely controlling rotation speeds for optimal separation while minimizing the impact on the samples. They also enhance safety by enabling balance control, detecting imbalances during rotation, and automatically stopping the centrifuge when necessary.

Additionally, in models requiring temperature regulation, micromotors can be used to drive fans, maintaining a stable environment for temperature-sensitive samples.

Automatic dispensing devices

An automatic dispensing device is used to dispense precise amounts of liquid with minimal manual work. By utilizing a high-performance micromotor, the syringe’s movement is controlled with great accuracy, ensuring precise sample loading and dispensing.

The device also handles X, Y, and Z axis movements to position the dispensing head with precision. Additionally, the device automates the replacement of syringe tips, manages liquid flow path switching through valve control, and mixes samples when necessary. These features streamline laboratory processes and ensure consistency in experiments or production environments.

Microscope stage control

When using powerful microscopes, precise adjustment of the specimen position is essential. High-precision positioning is required to achieve the fine adjustments needed for accurate sample observation. Micromotors are used to move the stage for this purpose.

Motors on the stage are used to move the specimen along the X and Y axes to change the observation position, while those on the objective lens or stage are moved vertically along the Z axis to adjust focus. After the position is set, the microscope can automatically scan a wide area of the specimen to capture images. Furthermore, the amount of light can be adjusted automatically using motorized aperture control, ensuring optimal lighting for clear observation.

All of this can be done precisely and consistently with micromotors.
