Understanding the Working of Brushless Makita Power Tools

Technological developments have recently had a great influence on the manufacture of power tools. Two of the most prominent results are the brushless motors and the battery amp-hour. While the former has been around for almost 50 years, only recently did it join the portable group in such collections as Makita power tools.

Universal Motors

In addition to wiring work and the bearings, the universal motor is composed of two major components: a stator and a rotor. While the stator does not move, it surrounds the rotor which is the center part. However, both have electromagnets, otherwise known as field windings, which fire on when there is presence of power.

Due to the magnetic attraction, the rotor is pulled toward repelling magnets located in the motor. A torque is created and the rotor spins. To keep it spinning and enable adjustment of rotation direction as well as speed, there is activation of the electromagnets by commutation.

Since the stator is fixed, it can get power supply through a connection of wires. On the other hand, the rotor is a moving component. Therefore, it gets its power supply through carbon brushes located against the commutator’s surface. Like in any other corded or cordless brushed motors, the commutator has different segments with the gaps between them responsible for timing and sequencing of the powering process of the rotor electromagnets through occasional contact.

Permanent-Magnet Motors

The stators in brushed cordless Makita power tools do not have windings since the small size of the magnets do not call for power. If provided with rare-earth magnets, the efficiency of permanent-magnet motors rises to top form. In addition, they have magnetic self-braking and perfect low-speed torque.

The brushless motor’s rotor has permanent magnets while the stator has electromagnetic windings. To get a clearer picture, think of it as a permanent-magnetic motor but this time turned inside out. Since the magnets need no power, a commutator and brushes are not required.

Keep in mind that a brushless motor does not have the mechanical switching present in a rotating commutator. Instead it is fitted with a very small onboard computer—known as a microprocessor—that enables electronic commutation through electronic switching. To control the speed and direction of the motor, the electrical pulses that pass to the electromagnets in the rotor are timed by electronics which monitor the position of the rotor.

Conclusion

Brushless Makita power tools come with numerous benefits. Since there is no rubbing of brushes against the commutator while there is the precision that comes with computer control, efficiency is enhanced. This is in addition to powerful but less noisy performance which can be improved by the addition of more features including multiple speed settings as well as soft –start and soft-fade. Brushless motors have also proved to be more durable simply because there is no wearing out of brushes.

Trends in Power Tools

More people around the world are buying up power tools, as Canadian contractors find business growing, and DIYers take advantage of new products from Makita Tools and other makers to do the work themselves. The value of the global power tool market is expected to pass $59 billion (CAD) by 2025.

Tool trends
While basics like hammers and wrenches are still must-haves for any toolbox, when it comes to sanding, cutting, and grinding, today’s workers naturally prefer power tools that make their tasks quicker and easier. Sales of cordless tools are rising, as more DIYers appreciate the mobility and ease of use. A turn to better rechargeable lithium-ion batteries provide more power and prolonged use times without the hassle and expense of extension cords. There is also a greater demand for versatility in oscillating and rotary tools that can perform different functions with the quick swap of a tool bit.

Construction Demand
The renewed growth of the Canadian housing market has led to an increase in construction jobs and thus the need for more power tools. North America, India, and China all see steady economic growth, and with it a need for more tools.
Asian and especially Chinese products are churning out a flood of power tools at affordable prices. Asia itself is becoming one the major global markets for power tools. Even in developing countries, a gradual rise in income and trends to urbanization are seeing a greater demand for these Asian products.

Product Development
Major players in the industry, such as Makita Tools of Japan, are putting more emphasis on product development to satisfy consumer expectation for safer, more versatile tools and better quality of construction. Sturdier, more ergonomic designs are required in the marketplace. Makita Tools has also been focused on incorporating more user-friendly features such as reduced dust emission, less noise, and lower vibration. They and other manufacturers must also take into account a growing number of consumer-safety regulations in many areas.

Power Tool Industry
The likelihood is that with increasing populations and housing needs, the power tool market will continue to grow. But with more competition from rival companies, there is a greater focus on marketing and product innovation. While the professional tools get more power and options for precision and utility, DIY homeowner versions are becoming more compact, colorful, and versatile.

The bottom line is that today’s power tool market offers a wider range of superior products to fit a wider range of needs.

Makita’s New 18V Battery and How It Will Make Your Job Easier

Makita Tools has been an innovator in power tools since 1958, and engines since 1915. Makita has developed a name for itself in the 100 years since, creating reliable and effective power tools for any job.

Recently, Makita Tools has redeveloped their 18V battery to extend the battery life of their popular LXT cordless lineup. Previous models of the battery produced 3.0 Amp-hours, where the newly-designed 18V doubles its capacity to 6.0 Amp-hours, complete with a fast charger capable of charging the high-capacity battery in less than an hour.

18V LXT Lineup

Makita Tools also offers a comprehensive line of products based on the single-battery 18V platform, known as the LXT line. Offering both brushed and brushless models, these tools provide plenty of flexibility to contractors needing a heavy-duty tool that is also very portable. Combined with the high-capacity LXT battery, your tools will be able to work 100% longer than before.

The newest tool in their LXT lineup is an 18V reciprocating saw. It is available either brushed or brushless for a controllable and reliable stroke per minute, which is completely adjustable for any situation with the use of a variable speed trigger. This tools also offers a “Tool-less” blade change, which makes it simpler to change blades whenever it is necessary. Not only this, the tool itself weighs less than 9 pounds with the battery attached, giving it plenty of maneuverability and ease-of-use.

Some other tools available in the LXT lineup are:

Cordless Multi-Tool
Brushless Driver and Hammer Driver
1/2″ Impact Wrench
6-1/2″ Circular Saw Kit
Plate Joiner
Caulk Gun
3-Speed Impact Driver
Rebar Cutter
4-1/2″ Angle Grinder
Brushless String Trimmer
Coffee Maker

Yes, Makita makes a battery-powered coffee maker that runs off its LXT batteries. This is particularly useful for those that love coffee, but have no access to electricity on the work site.

18V X2 Lineup

Makita offers many high-powered cordless tools that run using two 18V LXT batteries. This allows the tools to have uncompromising performance without the consumer having to buy into a new battery platform. Some of the tools available for this line are:

Brushless Reciprocating Saw
HEPA Backpack Dry Vacuum
7-1/4″ Circular Saw
Rotary Hammer
7-1/2″ Compound Miter Saw
Cordless Blower
Cordless Chain Saw

Makita has created an incredible line of cordless tools using a common platform, allowing any workers or contractors requiring a cordless solution to have every tool they need for the job. Combined with the new high-capacity 18V batteries, you will have tools that work as long as needed to get the job done.
