What is Prospine ?

Thank you very much for your visiting Prospine web site.



Our company was established in 1978 as metal mold parts manufacturer. And our sophisticated technology can make it possible to produce Erg’s highest grade camera platform. After the withdrawal of Erg, we have been producing and selling that platform under the name of Prospine.

At the beginning of 2000s, we started developing non-contact power transmission mechanism using attraction and repulsion force of magnet. The development utilized present technology of mold manufacturing and newly developed technology for analysis, magnetizing, measurement and so on.

We are now developing and manufacturing non-contact power transmission mechanism like magnet gear, magnetic-/electromagnetic-brake, magnetic clutch and so on under the brand name of Prospine, which is the same as our company name. At present our products are widely used in a variety of fields.

  

 

Advantages and applications of non-contact power transmission mechanism

The non-contact power transmission mechanism not only solves the problems such as vibration, wear, heat generation, lubrication, but also has the following merits like power transmission through wall, torque limit function, easy attaching and detaching, large tolerance for declination and eccentricity.

Application fields are widely spread and are conveyance in a clean environment, energy related fields, consumer products, train/automobile, fiber/ tape manufacturing, robots and so on.

If you apply “Prospine” in your machine, your design capability will become flexible without considering the condition of the traditional mechanism.

 

 

 

Technology

Prospine started as a metal mold manufacturer, so we have both equipment and technology to fabricate precision molds. Specifically they are cutting process, grinding process, electric discharge machining and thermos mechanical treatment by a vacuum furnace etc. This technology is also utilized to manufacture magnet products.

In addition, we developed new technology for the magnet products.

They are surface treatment to prohibit stain, design of magnetizing yoke, evaluation methods, magnetic field analysis and so on.  

  

Our featured technologies are as follows.

・Magnetic analysis technology

・Heat treatment of hysteresis material

 

Magnetic analysis technology

We have been deepening the analysis technology to enhance the simulation accuracy since we introduced magnetic field analysis technology. The left figure is the analysis model for soft magnetic material, and the right figure shows the analysis result and the measured value. It is said that the magnetic field analysis of soft magnetic material is difficult. However our analysis result is almost the same as the measured value.

We have been developing the products to satisfy customer’s needs based on this analysis technology.

Heat treatment of hysteresis material

We developed magnetic material uniquely and achieved high quality to meet the customer’s requirements. The left figure

shows a characteristics example of the material developed by the optimum aging treatment condition and the original composition, and the right figure shows the characteristics of electromagnetic brake developed using this material.

We can meet a wide range of requirements by enhancing torque characteristics based on the material improvement.

As stated above, we have been developing excellent magnetic products with the combination of our present technology and acquired technology.

Application

Our products are now used in a variety of applications.

We will show you several application fields with final products, and actual and potential components used in the products.

→ MOVIES (check out product samples!)

Standard

Miter

MP series

Use two magnets and magnetically joint them at 90-degree angle to change the direction. In this mechanism, the transmission ratio is in 1:1. two types of miter, “Cylinder&Cylinder” and “Disc&Cylinder”, are available. Please contact us for “epoxy electrodeposition coating”.

 

Miter.png

Cylinder&Cylinder

  • Space saving narrow pitch
  • Used high performance magnets

 

Disc&Cylinder  (Patented)

  • Since the area of contact between the disc and the cylinder magnet is larger than the double-cylinder type, more efficient torque is achieved.
  • No shaft bending
  • Easy torque adjustment
Cylinder & Cylinder Disc & Cylinder

ML series  (Aluminum)

Use two cylinder magnets and magnetically joint them at 90-degree angle to change the direction, which is similar use as MP series. Two sizes in the picture below were available in this series. These miter gears are impervious to external vibration and misalignment. The price of ML series is lower than half of MP series that became possible by changing the materials, the yoke to aluminum and the magnet to plastic magnet. No almite is treated on the product.

Plastic yoke type is discontinued.

 

  

Coupling


CP series

Place two cylinder magnets oppositely and magnetically join them. One transfers the torque to the other in 1:1 ratio. The followings are advantages of CP sereis.

  • Quick-release
  • Easy centering
  • Safe by a torque limiter function
  • Use like a lossless torsion spring
  • Transmit power to an isolated area parted by non-magnetic material,such as  aluminum, stainless, wood etc...

CI series    -Coaxial cylinder- 

Place two 18-pole cylinder magnets concentrically. One transfers power to the other in 1:1 ratio.

  • No thrust force
  • Transfer torque with absorbing a vibration in the axial direction
  • Safe by a torque limiter function

 

CO series   -Parallel axial cylinder-

Place two 18-pole cylinder magnets parallel. One transfers power to the other in 1:1 ratio.

  • Quick-release
  • Safe by a torque limiter function

Prospine linear slider is a linear actuator with magnet gears that ball screw rotates without contact. It is best for a use in a clean room since there are many advantages as with other magnet gears.

  • No wear no dust
  • Lubricant-free
  • No heat between parts
  • Improve cleanliness with Prospine products on the motor
  • Unnecessary to connect a power cable with the operation block, which leads to a total cost reduction.
  • Extendable sliders

 

Brake

A magnet brake with a torque limiter, there are two types of brakes available, “Eddy current” and “Hysteresis” in diameter 47 and 100 each. There are some good points below.

Brake shadow.png 

  • No wear no dust
  • Long-life operation without torque decreasing
  • Adjustable torque level
  • Simple installation
  • No wire

 

Eddy current brake         

This brake has no friction and no deterioration. Eddy current generates torque, which mechanism makes the brake non-contacted structure.

 

Hysteresis brake

Hysteresis was used in this brake and maintains amount of brake torque constant no matter how much revolution given. The volume of torque is adjustable by changing the location of the magnets' poles. These products are used especially in processes of film manufacturing, wrapping and bottle capping etc…
