Step motors for scientific laboratories - Tamagawa

Tamagawa develops its own technologies to enable scientific facilities to simplify and improve automated operations and enable constant work efficiency in the healthcare sector.

Step motors are widely used to perform procedures of maximum precision and repeatability within scientific research equipment such as gas chromatographs and devices for DNA analysis or biochemistry.

It features small size, light weight, high torque, and low price. This type of motor can be controlled more simply than a servo motor.
The rotation speed of the step motor is defined by the pulse frequency, while its rotation angle is defined by the quantity of pulses.

These digital signals perform open loop control, which does not require a feedback structure. On the other hand, the step angle of the unit is defined by the mechanical structure of a rotor and a stator.

– Capable of controlling precise position in open loop
– Capable of holding the static position stable by self-holding torque
– Capable of responding fast to the starting, stopping and reversing with its superior acceleration
– No maintenance is needed for the mechanical wear as is often the case with brushes for DC motors
