2 RoHS-Compliant Brushless DC Motor and Package BLH Series The BLH Series combines a slim, high-power brushless DC motor with a 24 VDC board-type driver, to meet your space-saving needs. Speed control range is 1 to 3 r/min. Choose from a wide variety, offering outputs of 15 to 1 W to meet your specific application. dditional Information Technical reference Page F-1 Safety standards Page G-2 List of safety standard approved products (Model, Standards, File No., Certification Body) Page G-1 Features Compact Board-Type The models with an output of 15 to 5 W adopt a compact, boardtype driver smaller than the size of a business card. This will certainly help to reduce the size of your equipment. Long Life Gearhead Rating of 1 Hours The rated life of the parallel shaft gearhead and hollow shaft flat gearhead is 1 hours. The parallel shaft gearhead achieves a rated life of twice as long as that of a conventional gearhead. 5 hours for gearhead equipped with 15 W geared motor. The 1 W parallel shaft gearhead has a tapped hole at the shaft tip. 72 mm (W) 55 mm (D) 27 mm (H) The 1 W driver has dimensions of 71 mm (D) 131 mm (W) 37.5 mm (H). Full Range of Functions The compact driver is packed with a full range of functions. Instantaneous stop Speed control via potentiometer Speed control by DC voltage cceleration/deceleration time setting larm output Speed Control Range 1 to 3 r/min (speed ratio 1:3) Wide Variety The series offers a wide range of models from compact packages with a motor output of 15 W, to larger ones producing a high output of 1 W. Choose one that best suits your specific requirements. IP65 Motor Structure The motor is protected against water intrusion, should water come into contact with the motor. IP4 for 15 W motor The motor must not be washed with water, and is not suitable for use in an environment where it constantly comes into contact with water. RoHS-Compliant The BLH Series conforms to the RoHS Directive that prohibits the use of six chemical substances including lead and cadmium. Details of RoHS Directive Page G-23 Features of Hollow Shaft Flat Gearhead Space-Saving and Low-Cost The output shaft can be coupled directly to a 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, allow you to reduce the size and installation space of your equipment. Since no shaft-coupling parts are needed, the parts cost and labor will also decrease. Installed Length Parallel Shaft Gearhead Coupling Gearhead Motor Coupling Space Hollow Shaft Flat Gearhead Space Saved High Permissible Torque While the permissible torque of the parallel shaft gearhead saturates at high gear ratios, the hollow shaft flat gearhead enables the motor torque to be fully utilized.

If both the STRT/STOP signal and the RUN/BRKE signal are set to ON, the motor rotates. The motor will accelerate over the time set by the acceleration/deceleration time potentiometer. During this time, if the CW/CCW signal is set to ON, the motor rotates clockwise as viewed from the shaft end of the motor; if the CW/CCW signal is set to OFF, the motor rotates in the counterclockwise direction. If the RUN/BRKE signal is set to OFF while the STRT/ STOP signal is ON, the motor stops instantaneously. If the STRT/STOP signal is set to OFF while the RUN/BRKE signal is ON, the motor will stop with deceleration time set by the acceleration/deceleration time potentiometer. The duration of each input signal must be 1 ms or longer. Do not operate (turn ON/OFF) two or more input signals simultaneously. There must be a minimum interval of 1 ms before another input signal can be operated after an input signal has been operated. 1 t least 1 ms 2 The direction applies to the motor alone. The specific direction will vary depending on the gear ratio. 3 The motor will start/stop over the time set by the acceleration/deceleration time potentiometer. Input/Output Signal Circuits Input Circuit The driver's signal inputs use the C-MOS input method. The signal status indicates a voltage level of to.5 V when the signal is ON, or 4 to 5 V when it is OFF. 5 V C-MOS Output from External Control Device 5 V C-MOS STRT/STOP RUN/BRKE CW/CCW INT.VR/EXT LRM-RESET 5 V Internal Circuit 1 kω 2.2 kω V V C-MOS.1 F Open-Collector Output from External Control Device Open- Collector V Switch Connection Switch STRT/STOP RUN/BRKE CW/CCW INT.VR/EXT LRM-RESET STRT/STOP RUN/BRKE CW/CCW INT.VR/EXT LRM-RESET 5 V 5 V Internal Circuit 1 kω 2.2 kω 1 kω 2.2 kω C-MOS.1 F V Internal Circuit C-MOS.1 F Use a switch capable of opening/closing the current flow at 5 VDC, 1 m maximum.

V V Internal Circuit 2SC2458 or Equivalent SPEED Output The system outputs pulse signals (with a width of.3 ms) at a rate of 3 pulses per rotation of the motor output shaft synchronized with the motor operation. You can measure the SPEED output frequency and calculate the motor speed. SPEED output frequency [Hz] Motor speed (r/min) SPEED output frequency (Hz) T.3 ms T LRM Output The LRM output is normally ON and goes OFF when there is an alarm. LRM-RESET When the motor is stopped, setting this signal ON, then returning it to OFF resets the alarm. Please return either the STRT/STOP input or the RUN/BRKE input to OFF before inputting the LRM-RESET. The LRM- RESET is not accepted if both these signals are ON. Notes: Output signal is open-collector output, so an external power supply (Vcc) is required. Use a power supply of no more than 26.4 VDC and connect a limit resistor (R) so that the output current does not exceed 1 m. When using neither the speed output function nor the alarm output function, this connection is not required.

External Speed Potentiometer PVR-2KZ (Sold separately) Speed [r/min] High Speed Multi-Motor Control Two or more sets of motor and driver can be operated at the same speed by using a DC power supply or an external speed potentiometer. When External DC Power Supply is Used Use a DC power supply with current capacity equal to or greater than the value obtained by the following expression. Current capacity (N is the number of drivers) I = 1 N (m) Example: When two drivers are used, current capacity should be at least 2 m. Connect the other input/output lines to each driver individually. Motor speed differences can be adjusted by connecting a resistor of 1.5 k, 1/4 W to the M terminal of the first driver, and a 5 k, 1/4 W variable resistor (VRn) to the M terminals of the other drivers.

External DC Power Supply 5 VDC 1 m min. 5 4 Resistance value (N is the number of drivers) VRx = 2/N (k ), N/4 (W) Example: When two drivers are used, the resistance is 1 k, 1/2 W. Connect the other input/output lines to each driver individually. Motor speed differences can be adjusted by connecting a resistor of 1.5 k, 1/4 W to the M terminal of the first driver, and a 5 k, 1/4 W variable resistor (VRn) to the M terminals of the other drivers. No more than five motors should be operated simultaneously when using the external speed potentiometer. 3 VRx 2 1 Control Line H CN2 M L 1.5 kω, 1/4 W H CN2 M L VRn 5 kω, 1/4 W Speed [r/min] 2 15 CN1 24 V CN1 24 V 1 5 Power Supply Line DC Voltage [VDC] External DC Voltage Speed Characteristics (Representative values) Note: The speed in the graph represents the speed of a motor alone. The gearhead output shaft speed of the combination type or geared type is calculated by dividing the graph speed by the gear ratio.
