Features | Brushless Motor BXII Series

Wide Speed Control Range 2~4000 r/min

Achieved speed ratio of 1:2000.

  Suitable for applications that require constant torque from low to high speeds.
(30~4000 r/min at analog setting.)

Stable Motor Drive

Speed Regulation ±0.05 %

Reduces speed variation due to changes in the load (load fluctuation) and the change of ambient environment (changing ambient temperature, voltage fluctuation).

Flutter Characteristics Effective Value: Approx. 0.1 %

The effective value of the flutter characteristics, which represents speed fluctuations of motor rotation, is about 0.1 %. (Reference value at rated speed)
Even when rotating at a certain speed, there will be slight fluctuation in the actual speed around the target rotation speed. The speed fluctuations are known as flutter.

Supports Multi-Speed Operation with Up to 16 Speeds

Up to 16 points of operation data, such as operating speed and acceleration/deceleration time, can be set.

Operation and Switch Up to 16 Data Points With Just I/O

You can set up to 16 points of operation data such as travel amount and operating speed.

Linking Multiple Operation Data

In addition to single data setting, you can also set linked operation, which combines multiple operation data.

• *Dwell time is the wait time until the next positioning operation starts.

Continuous Rotation in the Same Direction is Possible

The command position and multiple rotation data can be returned to 0 if the command position exceeds the "wrap setting range" parameter value. Since the multiple rotation data is returned to 0, continuous rotation in the same direction is possible.

All models can be selected with or without an electromagnetic brake. The electromagnetic brake is automatically controlled to turn ON/OFF according to the operation command signal to the driver.

Capable of Vertical Operation (Gravitational operation)

With an electromagnetic brake, stable speed control is possible even when driving vertical operation.

During vertical operation, regenerative energy is generated. Use a regeneration resistor (Sold separately).

Capable of Position Holding When Stopped

Position holding when driving in a vertical direction^* or horizontal direction is possible.
When driving horizontally, it is possible to set servo lock at motor standstill, which excites the motor to generate a holding force.

• *For vertical operation (gravitational operation), use a product with an electromagnetic brake.

Prevents Loads From Falling in an Emergency

The electromagnetic brake is of the power off activated type, so it works automatically even when power is lost in a blackout. Instantly stops the motor and prevents the load from falling.

Electromagnetic brake structure and service life｜Technical reference

It can be used for applications that require adjustment of torque and tension, such as tension (brake), pushing (pressing), and tightening.

• Tension - As a Brake to Gain Tension

  

• Pushing - For Printing and Other Press Applications

  

The setting range of the maximum instantaneous torque of the motor can be limited from 0 to 250 % in 1 % units.

• Torque limiting accuracy ±10 % approx. (relative to rated torque)
• Torque limiting can be switched ON/OFF with an external signal (TL input)

Easy Setting and Start-Up With MEXE02 Support Software
