The Brushless DC Motor Advantage

Brushless DC Motor Construction

The brushless DC motor features a coil is star-wired (Y-wired) with three-phases: U, V, and W and is located in the stator, and the rotor is made of magnets magnetized in a multi-pole configuration as shown in Fig. 1.
Inside the stator, three hall ICs are arranged as magnetic elements so that the phase difference of the output signal from each hall IC will be 120 degrees apart for every rotation of the rotor.

Compact Yet Powerful

Brushless DC Motors are very compact and when mated with a gear head, can produce a large amount of torque.

Compact, High Powerful

Excellent Speed & Torque Performance

Speed-Torque

Space Saving

The compact yet powerful brushless DC motor incorporates permanent magnets in the motor rotor. Compare with an AC motor having a frame size of 3.54 in. (90 mm), a brushless dc motor of the same specifications is 2.95 in. (75 mm) shorter and offers 1.3 times more output.

The compact motor structure lets you downsize your equipment.

Compact, Powerful Motor

Energy Saving

Brushless DC (BLDC) motors, which incorporate permanent magnets in the rotor, generate little secondary loss from the rotor.

At an output power of 1/12 HP (60 W), for example, the power consumption of the BLF Series Brushless DC Motor is approximately 23% less than that of an inverter-controlled AC motor, which enables the energy-saving operation of your equipment.

Energy Saving

No Brushes = No Maintenance

The brushless DC motors do not utilize brushes, which often require replacing and/or maintenance, saving time and cost.

No Brushes = No Maintenance

Electronic-Input Control

Brushless DC motor systems are available with electronic-input control. The driver can be connected directly to a programmable controller. As the motor requires no power relays, there is no need for periodic service or replacement of relays. this makes the machine highly reliable. Moreover, the time required to set up the motor is greatly reduced. Removing the relays eliminates the spark noise during opening and closing of the relay contact points.

Features

Parallel Shaft Gearhead
Parallel Shaft Gearhead

A dedicated high-strength gearhead for brushless DC motors that also supports high-speed rotation.
Incorporating a long-life design, this gearhead has a rated life of 10,000 hours, which is twice as long as the rated life of a conventional gearhead.

Flat Hollow Shaft Gearhead
Hollow Shaft Flat Gearhead

This gearhead adopts a hollow shaft that can be directly coupled with the drive shaft of your equipment without using any coupling part.
The flat structure embodies higher strength and higher permissible torque than conventional parallel shaft gearheads.

 

Features of Hollow Shaft Flat Gearhead

Our hollow shaft flat gearhead for brushless DC motors incorporates a special structure offering space-saving solutions for your equipment and realizing high permissible torque.

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 the front or rear face or by using a 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.

Space-Saving

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.

Torque

Selectable Installation Direction

If you are installing the hollow shaft flat gearhead, the gearhead can be oriented in any of the four directions according to the equipment.

Installation

High Reliability

Use of a belt and pulley, chain and sprocket as shaft-coupling parts may necessitate maintenance due to elongation of the belt or chain, dust or loss of lubrication oil. The hollow shaft flat gearhead adopts a sealed gear transmission structure, which embodies high reliability while eliminating the need for maintenance. This gearhead also lasts long, as its rated life is 10,000 hours.
