This is a product utilization example of Uratani Engineering, which performs trial production and mass production of coils and motors.

Did you know that coils are used in various locations in a vehicle?Although round wire has been used in conventional coils, they have reached their limits in terms of performance.

URATANI ENGINEERING manufactures coils that utilize flat wire in order to increase the space factor compared with conventional wire.Coils are the unsung heroes that support vehicle performance.Our coils have contributed to the development of the automotive industry.To date, we have done business with more than 300 companies in this field.

Vehicles are equipped with various electronic devices that use different voltages, such as engine control units (ECUs), lights and audio systems.Today, the range of equipment is becoming even more diverse with car navigation systems, smartphone integration, and so on.DC/DC converter is a unit that transforms the power of a battery or generator to match the device.

In recent years, in part due to advancements in the practical application of electric vehicles, that has been a rising demand for compact and efficient DC/DC converters, but there are limits to how small conventional coils can be made.With edgewise coils using our flat wire, we can reduce size while increasing the space factor.

An inverter is a power supply circuit that converts DC power into AC power.By converting the DC power supplied from a vehicle battery into AC power to drive an AC motor, electricity can be used inside a vehicle.

When conventional round wires are used in inverter coils, efficiency is degraded and there are limits to size reductions, so reducing the weight of the inverter coil results in degraded performance.Coils that utilize our flat wire produce inverters with high performance and a more compact size.

A motor is a component that uses electricity to generate kinetic energy to move the various parts of an automobile.With the electric vehicles that have appeared in recent years, a motor takes over the role of an engine in a gas-driven vehicle. As a result, motors are highly expected to be at the heart of automobiles in the future.

An automotive motor needs to be compact and produce a large current.While not possible with round wire coils, motors that use flat wire can be made smaller.

A battery is a device that stores the electricity created by an alternator (generator) equipped in a vehicle.The battery places the main role in supplying generated direct current (DC) electricity throughout a vehicle.

With electric vehicles now becoming commonplace, there is a growing demand for compact, high-capacity lithium-ion batteries.By utilizing flat wire, URATANI ENGINEERING is able to produce batteries that are compact and high-capacity, something not possible with coils made from round wire.

Among bearings designed to ensure the smooth rotation of shafts in industrial machinery, magnetic bearings are characterized by their contactless support of shafts.This is to minimize friction and resistance during rotation as much as possible.This allows for high-speed rotation while keeping vibrations and noise to a minimum.Another advantage is that lubricant is not required, and the minimal wear and tear on rotating components removes the need for replacements.As the position of the shaft can be observed using sensors, abnormal light modulation can also be quickly detected.

A power conditioner (reactor) is a type of inverter used when converting generated power. Due to the widespread adoption of solar power generation, there are demands for products with reduced size for household use.URATANI ENGINEERING uses flat wire for its step-up voltage coils to make them more compact, increasing the space factor and achieving low loss and low noise.These technological capabilities can be applied not only to solar power generation for household use, but to industrial machinery as well.

For companies that deal with electricity, transformers (voltage and current transformers) could be described as the foundation of their business.These devices, which are used in a wide array of fields from housing equipment to home appliances, factories, impeller equipment and so on, must be designed and manufactured in consideration of usage environments, degradation over time, and other factors.URATANI ENGINEERING has leveraged its expertise in flat wire-based coils to successfully produce higher frequencies than transformers based on round wire coils while reducing size at the same time.

Manufacturing the coils used as the electrodes for welders is another area where URATANI ENGINEERING boasts expertise.As with power conditioners (reactors), the use of flat wire in step-up voltage coils improves space factor and efficiency.Component sizes are also reduced.URATANI ENGINEERING specializes in made-to-order products, but also has mass production systems in place.We present customers with prototypes that meet their needs.

We are also involved in the manufacturing of chip mounters that are arranged on a substrate before the electronic components are soldered.In addition to rotary mounters that can mount micro-sized chips at high speed, we can also propose module mounters that can accommodate a wide range of components, delivering proposals for products that are faster and more compact to meet customer needs.

You can also entrust URATANI ENGINEERING with the manufacturing of drive motors, which convert electrical energy into mechanical energy.A drive motor plays the same role as an engine in a gasoline-powered vehicle. The drive motors we work on can be used in electric vehicles and hybrid vehicles, both of which have achieved widespread adoption in recent years.Applying our unique coil manufacturing technologies that involve the processing of flat wire, we can propose drive motors to suit customer needs.

While a regular motor employs a rotational design, a linear motor stretches on a line in the direction of motion.URATANI ENGINEERING assists in the production of machines based on linear motor drive systems that levitate, propel and guide using magnetic forces.Contactless linear motors are ideal for machinery designed for precision processing due to the lack of mechanical friction or rattling.

While semiconductor fabrication equipment requires precision down to the micrometer and nanometer levels, it can be adversely affected by high frequency noise entering from the power supply line.Our flat wire-based filter coils (choke coils) boast large currents with a high space factor, supporting the proper operation of precision devices and preventing damage or degradation due to overcurrent.

Robots are now utilized in various industries, from industry to agriculture.Depending on the intended use, robots need motors that are small, powerful and are capable of accurate control, in order to make the robots more compact.

URATANI ENGINEERING manufactures motors for use in robots that are more compact and provide a higher current thanks to edgewise coils that use flat wire.This leads to the manufacturing of compact and powerful robots that are technically impossible with the use of round wire.

Technologies that make use of coils are also used in medical MRI units, which harness magnetic forces to image the inside of a patient at high resolution.While medical equipment requires large current coils, conventional round wire-based coils have come up against limitations.

URATANI ENGINEERING has contributed to the development of MRI units that are more compact and provide a higher current thanks to coils the utilize flat wire.

An accelerator is a device that accelerates charged particles, which are particles that carry an electrical charge.In medical facilities, accelerates are applied for cancer treatment, the devices are also utilized for experiments on atomic and sub-atomic particles.。

An accelerate is a large piece of equipment, and requires a large current for use.It was not possible to create a large-current coil using a conventional round wire-based coil, but coils that use flat wire can be manufactured for use in accelerators.
