The BX Series brushless motor and driver packages offer high performance and high function. The full lineup covers a wide output range from 30 W (1/25 HP) up to 400 W (1/2 HP). When using with a control module, the BX Series provides the torque limiting, position control and other extended functions, in addition to the high performance speed control function offered by the standard model.

The BX Series offers a wide speed range of 30 to 3000 r/min and provides flat torque at all speeds from high to low. The high starting torque characteristics ensure ample torque at start and stop.
The BX Series offers highly accurate speed control, achieving an excellent speed regulation with respect to load.
Speed Regulation:
With the BX Series, rotational irregularity at medium and high speeds is also reduced substantially.

The motor with an electromagnetic brake enables stable speed control even during vertical drive (gravitational operation). When the power is turned off, the motor stops instantly to hold the load in place. The electromagnetic brake is automatically controlled via the driver in accordance with ON/OFF of the operation command signal.
Long Life GearheadThe high-strength gearhead is designed to withstand high-speed revolutions. The rated life of the gearhead is 10000 hours*, which is twice as long as that of our previous 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.
High 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.
You can extend the functions of the BX Series using an optional control module (OPX-1A). The following functions are available on the extended system:
Speed can be set digitally using an optional control module. You can set up to eight different speeds.

The digital speed setting function expands the speed control range to cover 3 to 3000 r/min.

When using a control module (Digital Setting):
Position control can be performed with the BX Series simply by setting data using the optional control module. The resolution is 0.72° (500 pulses per rotation) and a maximum of six points of positioning data can be set, of which two can be set for continuous operation. Return to mechanical/electrical home operation can also be performed.

Use of the optional control module enables torque limiting. The torque limiting function suppresses the motor output torque in accordance with the application and use condition.
RoHS (Restriction of Hazardous Substances) Directive:
Directive on restriction of the use of certain hazardous substances in electrical and electronic equipment (2002/95/EC).
The RoHS Directive prohibits the use of six chemical substances in electrical and electronic products sold in the EU member states. The six controlled substances are: lead, hexavalent chromium, cadmium, mercury and two specific brominated flame-retardants (PBB and PBDE).
