ピーエス特機 List of Products and Services

We have developed a coreless frameless motor that utilizes a rare-earth anisotropic magnet. The rare-earth anisotropic magnet effect has achieved approximately a 20% increase in torque. Note: A rare-earth anisotropic magnet is a groundbreaking magnet that realizes a Halbach array in a ring magnet, concentrating magnetic flux on the opposite side with just one magnetization.

• Brushless DC Motor

We have developed a frameless motor that uses extreme anisotropic magnets. In the cored motor, we have also adopted square wire, achieving approximately a 40% increase in torque compared to the standard type. Note: Extreme anisotropic magnets are revolutionary magnets that realize Halbach field magnets in ring form, concentrating magnetic flux on the opposite side with just one magnetization.

We have added a high-output version to our lineup of frameless motors. By introducing the latest trends in each material, we have achieved double the output compared to existing frameless motors. Laminated core: Permendur Magnet: Highly anisotropic sintered neodymium Winding: Square wire We will respond to your needs for downsizing and high output with "custom" solutions!

• DC Motor

A motor that uses windings instead of permanent magnets in the rotor, thus "not using permanent magnets." Since there are no magnets, by varying the amount of current supplied to the coils wound on the rotor, it is possible to vary the generated magnetic flux, enabling control similar to field weakening in IPM types, which expands the range of variable speeds compared to IPM motors. Without magnets, rare earth materials are, of course, unnecessary! It is an environmentally friendly eco-motor. Currently under development, we are also seeking joint research with universities and collaborative development with companies regarding materials and configurations.
