Flat Torque CurveWide Speed Control Range and Flat Torque

The maximum motor speed of the BLF Series is 4000 r/min, which is higher than the 3000 r/min achieved by our previous products. The speed control range has also expanded to cover velocities from 80 to 4000 r/min (speed ratio of 50:1; measured at the motor shaft), thus allowing you to program operations at various speeds from low to high.


 

Slim, Yet Powerful Design

A slim body and high output are two key features of a brushless motor. The BLF Series does not disappoint the users expecting these attributes. From its space-saving compact body in frame sizes from 2.36 in. (60 mm) up to 4.33 in. (110 mm), the BLF produces a high output from 1/25 HP (30 W) up to 1/2 HP (400 W).

Speed Setting Four Speed Setting Methods

The BLF Series lets you control speeds using one of four methods. Select internal potentiometer, digital operator, external potentiometer or external DC voltage according to the condition in which your equipment is used.

Internal Potentiometer
Turn the built-in speed setting knob on the driver to set a desired speed.

Digital Operator
Directly enter a desired value using the operation keys on the digital operator located on the driver's front panel.

External Potentiometer
You can use an optional external potentiometer to set speeds at a location away from the driver.

External DC voltage
Speeds can be set by connecting an external DC power supply and supplying DC voltage to the driver. The BLF Series supports two DC power supplies of 5 VDC and 10 VDC.

Remote Control Kit Digital Operator

The driver of the BLF Series comes standard with a digital operator that can be used as a data setting unit and display. Using the operation key, you can input speed settings digitally in no time. The digital operator also provides full driver functions, such as:

  • Three speed display modes
  • Multi-speed operation using up to eight speeds
  • Four speed setting methods
  • Various protection functions

Detachable Digital Operator

The digital operator, which serves as both a data setting unit and a display, can be detached from the driver and used at a location as far as 16.4 ft. (5 m) away using an optional remote control kit. Use the digital operator as a handy operation unit or a display outside the distribution panel. (The digital operator conforms to IP65 when the remote control kit is used.)

Different Speed Display Modes

The BLF Series supports three speed display modes. Choose the mode that best suits your application.

Motor speed display [r/min]
In this mode the speed of the motor shaft of gear output shaft is displayed.

Conveyor speed display [m/min]
In this mode the transfer speed of the work on a conveyor, etc. is displayed.

Load factor display [%]
In this mode the actual load is displayed as a percentage of the rated load being 100%.*
*A maximum error of approx. 20% may generate when the motor is operated at the rated speed under the rated load.

Multi-Speed Operation

The BLF Series lets you program multi-speed operations. Up to eight speeds can be set and registered, and selected freely using external signals.

Speeds can be set in units of 1 r/min on the digital operator and a different acceleration/deceleration time can be set for each speed, thus allowing creation of diverse profiles for various operation patterns of your equipment.

Speed Teaching Function

The speed teaching function allows you to set speeds by physically operating the motor. It's an easy way to set speeds regardless of the mechanism of your equipment.

Various Protection Functions

The BLF Series detects various motor and driver errors such as overload, overvoltage, low-voltage, missing phase, overspeed, over current, EEPROM error, CPU error, operation error and external error. Upon detection of an error, the driver will immediately stop the motor and output an alarm signal.

Switchable Sink/Source Inputs

Select the ink mode or source mode for the input terminals. You can change the setting at any time.

Easy Wiring

By separating the motor cable and signal cable, the BLF Series is less vulnerable to noise and thus allows for an extension of the motor/driver wiring distance to a maximum 65.6 ft. (20 m). [Select an optional connection cable set from among the eight lengths of 3.3 to 65.6 ft. (1 to 20 m)].

IP65 Protection*

The motor (excluding the mounting surface on the round shaft type and the connector) and digital operator (when an optional remote-control kit is used) provide a high level of protection conforming to IP65. It means you can use the BLF Series in locations where the unit may come into contact with water.

*The BLF Series is not designed for washing directly in water or use in an environment where the unit constantly receives water splashes. The protection class of the driver is IP20.

Space SavingHollow Shaft Flat Gearhead

Space-Saving and Low-Cost
The output shaft can be coupled directly to your drive shaft without using a coupling. The flexible installation modes, such as installation on either the front or rear face or by using the center shaft, allows you to reduce the size and installation space of your equipment. Sine no shaft-coupling parts are needed, the parts cost and assembly man-hours will also decrease.


Higher Permissible TorqueHigh Permissible Torque
While the parallel shaft gearhead lets the permissible torque saturate at high gear ratios, the hollow shaft flat gearhead enables the motor torque to be utilized to its maximum capability.
