Brushless DC Motors (BLDC Motors)

Brushless DC motors have slim bodies and provide high output and high efficiency due to the built-in permanent magnets. The built-in sensor (hall IC) constantly monitors the motor's speed. No matter the load conditions, feedback control is carried out at all times so that the command speed and actual speed remain constant.

Speed stability with feedback control

Brushless DC motors compare the setting speed with the speed feedback signals from the motor at all times and adjust the motor's applied voltage. Speed is kept stable over the entire speed range from low to high even when the load fluctuates.

Speed Stability

IE4-equivalent* high-efficiency and energy-saving motor

Brushless DC motors are higher efficiency than three-phase motors (induction motors).

High Efficiency Motors

Broad speed control range and flat torque

Rated torque is consistent over the entire speed range from low to high. Sufficient torque is obtained without limiting the used torque at low speeds, as is done with three-phase motors when driven with an inverter.

Speed-Torque

Compact, lightweight and high power

Since these are brushless DC motors with built-in permanent magnets, they offer high output even though they are compact. Installation is easy and both equipment weight and space can be reduced.

Motor Types

Types to suit a variety of environments are available, including the connector type with selectable cable length and motors conforming to IP65 rating for degree of protection. For applications in which holding is required during horizontal operation, Oriental Motor offers motors with an electromagnetic brake.

Increase Performance and Value with New Drivers

Reduction in Equipment Tact Time

Suitable for Applications in Quiet Environments

Noise Value approx. 44 dB (reduced by approx. 13 dB)

Noise sounds about half as loud as conventional products.

*30W with parallel shaft gearhead (5:1)
*Measurement of noise: OA value

Noise Reduction

The BLH Series uses a sinusoidal drive method. With little torque ripple and smooth, stable rotation even at low speeds, the motor's drive sound is reduced.

Synchronized Operation and Operation with Little Speed Fluctuation

Startup and Maintenance with Digital Settings + Support Software

Equipment Startup Assistance

Teaching Function

Operating data can be set on the computer screen. It is possible to perform a test run without connecting the host system, then record the operating data as-is.

Operating Data Copy Reading

Copy the operating data to the driver when using multiple units and read out the data on the driver side. This contributes to reduced system startup time.

Predictive Maintenance with Visualization

What is predictive maintenance? By constantly monitoring the status of the motor and performing maintenance when signs of change are observed, trouble can be avoided.

Torque Adjustment

Besides applications such as adjustment of tightening force, it can also be used as a safety measure for pinching detection and equipment damage prevention. he max. instantaneous torque range can be set between 0 and 200% by assuming the rated torque to be 100%.

Load Holding Function (RS-485 or Digital Type)

The load holding function can be used to electrically hold* the load in place without an electromagnetic brake. For example, work can be performed on the load when it's held in place on a conveyor.

*It can hold a load with a rated torque of up to 50%.

Note: When the power supply to the driver is turned off, the holding torque is lost. It cannot be used to prevent falling when stopped.

Load Holding

No need for a maintenance

It is also suitable for applications where the load needs to be stopped frequently. Since there are no mechanical parts, it contributes to a longer life.

Load Holding

Space saving of equipment

Since no mechanical brake is required, it contributes to space saving and weight reduction in the device.

Operating Data Setting

When using the digital setting type, operating data for up to 8 points can be set.

Long-Life, Parallel Shaft Gearhead

15 W (1/50 HP)
30 W (1/25 HP)
50 W (1/15 HP)
100 W (1/8 HP)

The 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.

*5000 hours for gearhead equipped with 15 W (1/50 HP) brushless DC motor.

Up to 260 lb-in of Torque Possible
[100 W (1/8 HP) Brushless DC Motor with Parallel Shaft Gearhead]

Flange Drive Adapter available for 100 W (1/8 HP) Parallel Shaft Gear Motors

Permissible load has been increased by mounting with a parallel shaft gearhead. Direct mounting of the rotation mechanism to wheels or rotary tables has been simplified, which helps reduce design time.

CS (Center Shaft) Gearhead

30 W (1/25 HP)
50 W (1/15 HP)

Reduced Equipment Size and Increased Load-Bearing Capacity

With characteristics such as “increased load-bearing capacity/next-level torque/center shaft”, the CS Geared Type not only makes equipment faster and more compact but also contributes to improved freedom of design for customers.

Increased Load-Bearing Capacity Compared with Parallel Shaft Gearhead

Achieves Next-Level Torque with Same Frame Size

Simplified Design

With no eccentricity, CS geared motors contribute to the simplicity of equipment design.

Structure of Center Shaft Gear

The center shaft gearhead has been achieved by positioning the large gear so that it is free of the central axis.

Hollow Shaft Flat Gearhead

30 W (1/25 HP)
50 W (1/15 HP)
100 W (1/8 HP)

Permissible Torque without Saturation

The hollow shaft flat gearhead enables permissible torque without saturation even at high gear ratios. The motor torque can be fully utilized.

High Torque

Low Cost

By eliminating parts such as a coupling or belt-and-pulley, the parts cost and labor will also decrease.

Low Cost

Space Saving is Achieved with a Hollow Shaft Flat Gearhead

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. Since no shaft-coupling parts are needed, the parts cost and assembly man-hours will also decrease.

Space Saving

Electromagnetic Brake

30 W (1/25 HP)
50 W (1/15 HP)
100 W (1/8 HP)

Stop and Hold Using Electromagnetic Brake

The stop position can be maintained when stopping the equipment to load and unlock or process work pieces.
Hold loads during unexpected occurrences such as power outages.

Conﬁrm motor is stopped by MOVE output

The electromagnetic brake release timing can be conﬁrmed using the MOVE output for digital setting type and RS-485 communication.
