Easy, Afforable Speed Control

High Performance Speed Control

The BMU series brushless DC motor speed control system offers a maximum speed of up to 4000 r/min (80 to 4000 r/min). This allows for a wider speed range, wider selection of gear ratios and torque ranges making the BMU Series an ideal alternative for servo, brushed motors or AC three-phase Inverter driven applications.

High Performance Speed Control

Affordable Price

The BMU series brushless DC motor speed control systems offer user-friendly features and expanded functions at an affordable price. Now offering even more value and performance, the BMU series BLDC motor, driver and gearhead come together as one part number; saving time when ordering and ensuring a complete solution, guaranteed.

No Maintenance, Longer Life

In a brushless DC motor, there are no brushes and thus no physical contact the could lead to frictional energy losses.

While brush DC motors use a brush and commutator to rotate and require regular maintenance, Brushless DC Motors (BLDC Motors) rotate by the ON/OFF operation of the drive circuit transistor, based on the signals detected by the hall effect IC (magnetic sensor).

Brushless DC Motors (BLDC Motors) are more expensive to design and manufacture, however, they are typically more efficient than brushed DC motors.

This leads to:

No maintenance, longer life
More power
Longer runtime

Easy Speed Control

Using the dial and digital speed indicator, controlling the BMU series brushless DC motor speed is simple and user-friendly.

Turn the dial and set the desired speed. Push to set (store) the desired speed. After the speed has been set, it can easily be changed by operating the dial. The dial can be locked to prevent changes in speed with the dial lock operation.

Easy Wiring, Easy Set Up

Get started quickly and easily. Connecting the motor is simple using the included cables with connectors. The power and I/O connectors feature a screwless connector, eliminating the need for soldering or crimp tools. Start the motor with one switch; the motor starts when the switch is set to "RUN" and decelerates to a stop if set to "STAND-BY". It's also simple to change the rotation direction of the motor using the rotation direction switch on the front of the driver.

A New Motor Design: Compact, High-Power and High-Efficiency

An optimal magnetic design and high-performance material enable the new brushless DC motor stator plate to have a thickness of just 7/16 in. (11.2 mm). This slim design achieves a highly efficient power unit that outputs 120 W (1/6 HP). Compared with the conventional brushless DC motor of the same output power, the stator plate thickness is only half of the conventional one.

High Performance Stator

Degree of Protection IP66

The connector is newly developed for small motors and enables a direct connection between the motor and driver. Connecting is easy due to the lock lever that does not require screws. Also, the motor structure has achieved an IP66* degree of protection for its improved watertight and dust-resistant performance. The internal gasket and O-ring improve the watertight performance.

*The degree of protection and output shaft material vary depending on the types of gearheads combined. See the product lineup for details.

Easy Connector

Selectable Cable Outlet Direction

Two types of the connection cables are available, depending on which direction the cable will be drawn. Since a single connection cable can connect directly between the driver and motor at a distance of up to 20 m (65.6 ft.), no extension cable is required.

Load Factor can be shown

With the rated torque of the motor at 100%, the load factor can be expressed as a percentage (40-200%). The load condition during start-up, as well as the load condition due to the aging deterioration of the equipment can be confirmed.

Dial Operation Lock Function

This prevents the undesired changes in the speed and the changes or deletion of data with the operation of the dial. At the main screen for each operating mode, press the "MODE" key for 5 seconds or more. When "Lk" appears the lock function is activated.

Lock Function

Canceling the Lock Function

Return to the main screen and press the "MODE" key for 5 seconds or more. When "UnLK" is indication the lock function has been cancelled.

High-Strength Gearhead

High strength is achieved through improving the strength of gears through heat treatment and through larger bearing diameters. The high permissible torque is 2 ~ 3 times that of a gearhead for an AC motor with the same frame size, and this contributes to reducing the size of equipment.

New Gearhead (combination type)

With the gearhead's boss and machined mounting surface, the installation accuracy has been greatly improved. The new gearhead also has lower audible noise as compared to our previous type and comes pre-assembled (motor and gear) as a combination type.

Long Life

A long life gearhead that uses a special bearing and grease for high speed rotation.

A rated life of 10000 hours is achieved.

Tapped Hole at the End of the Output Shaft (GFV Gear 80 mm (3.15 in.) min.)

A tapped hole has been machined at the tip of the output shaft. This can be used as an aid for preventing transmission parts from coming off.

Shaft Hole

Standardized Use of Stainless Steel Shaft

These brushless DC IP66 motors include a shaft made of SUS303 type steel, which provides excellent rust prevention and corrosion resistance. Stainless steel is also used in the parallel keys and installation screws.

Pre-Assembled Motor & Gearhead

Space Saving

Space reduction is achieved when mounted along side the conveyor belt. Because the output shaft of the gear is vertically in the middle of the installation surface, it is possible to change the installation direction horizontally, tailored to equipment position of installation.

Space Saving

Low Cost

Component cost saving is achieved through reduction of fastening parts, assembly steps reduced through mechanism simplification. Maintenance cost is also reduced or eliminated as a result.

Space Saving Design

Flexible Installation

The gearhead can be removed and the assembly position can be changed in 90˚ increments. The connector positions can also be changed to suit the equipment.
