Rotary Components

Hybrid stepping motors

QMotor vibration and noise become severe at specific speed ranges. What is the cause?

A

This is likely due to the "resonance" phenomenon characteristic of stepping motors. You need to either avoid these speed ranges or change the driving method.

Resonance occurs when the natural frequency of the motor matches the input pulse frequency. Countermeasures include programming to quickly bypass the resonant speed band or changing to a driver with a "microstepping" feature, which finely divides pulses for smoother rotation.

PM stepping motors

QI want to run a PM stepping motor at maximum speed, but the torque drops abruptly and it stops. What is the cause?

A

This sudden torque drop-off is a fundamental physical limitation caused by back electromotive force (back EMF) and coil inductance, which restrict current flow at higher speeds.

As the motor’s speed increases, the motor acts like a generator, producing a reverse voltage. Overcoming this back EMF to drive current requires a higher driver power supply voltage.

Vacuum Pump (under development)

QWhat causes increased noise and vibration during pump operation?

A

The primary causes are typically bearing wear due to aging or the end of the diaphragm lifecycle. Replacing the cartridge pump unit is recommended.

Although our product features a long-life design, exceeding the specified service life can lead to increased noise and vibration.

QIs it necessary to install an air filter on the suction side?

A

If the workpiece may carry dust or debris, installing an air filter is strongly recommended to protect the pump and preserve performance.

Debris trapped in the diaphragm or valves reduces vacuum pressure and causes insufficient flow. Installing a compact inline filter between the suction pad and the pump can significantly reduce failure rates.

QIs it possible to customize the pump to achieve our required flow rate and vacuum pressure?

A

Customization beyond standard catalog specifications is available, subject to minimum order quantities (MOQs).

We can propose optimizations tailored to your application, such as adjusting motor speed by changing the windings or modifying materials based on your operating environment. Please contact us with your detailed requirements.

Fan Motors

High-pressure blowers

QAre blowers repairable?

A

No, we do not repair blowers
We sell blowers for maintenance purposes.

Sensing Devices
