Hybrid stepping motors

Driven by electrical pulse signals, these stepping motors rotate at precise angles to ensure highly accurate starting, stopping, and positioning through open-loop control. Hybrid stepping motors integrate a permanent magnet within a laminated silicon steel rotor. By incorporating our high-precision NMB ball bearings, they deliver superior accuracy and reliability.

To meet diverse design requirements, the MinebeaMitsumi hybrid stepping motor lineup includes standard, linear, geared, and encoder-equipped models.
We also offer detailed customization to suit specific applications. For more information, please refer to the "Custom guide." Additionally, CAD data and data sheets detailing product features and applications are available for download.

FAQ

QWhere are the hybrid stepping motors manufactured?

They are manufactured in Lopburi, Thailand.

QCan I purchase from a single unit for sample use?

We offer "standard catalog models" available for order from just one unit for prototyping and evaluation.

We have a lineup of 40 "standard in-stock models" that can be shipped within two weeks with a minimum order quantity (MOQ) of one. We provide dedicated support and after-sales service even for small-lot orders, so please feel free to contact us.

QWhat are the differences between Permanent Magnet (PM) stepping motors and hybrid types?

Hybrid stepping motors feature finer step angles, providing higher resolution and greater torque output than PM types.

While PM types have a simple structure and are low-cost, hybrid models incorporate a gear-toothed magnetic core and a permanent magnet in the rotor. This design makes them highly suitable for industrial equipment requiring precise positioning and high power output.

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

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.

QWhat is the lifespan of a hybrid stepping motor? Does it require regular maintenance?

The motor's lifespan is essentially determined by its internal bearings. Since there are no wearing parts like brushes, they are virtually maintenance-free over long periods.

Under normal conditions, they boast a lifespan of tens of thousands of hours. However, excessively high ambient temperatures or applying radial (lateral) or thrust (axial) loads exceeding specifications will accelerate bearing wear. Designing your system within the tolerances specified in the data sheet is crucial for maximizing service life.

QHow do they differ from servo motors, and which should I choose?

The primary advantages of stepping motors are the elimination of complex setups like gain tuning, combined with high low-speed torque and strong holding power at a standstill.

Servo motors are preferable when high-speed operation or rapid response to sudden load changes is critical. Conversely, hybrid stepping motors are recommended when exact positional holding is required or when implementing simple, cost-effective open-loop control.
