MR type (Round core linear motor / Compact size) - Industrial robots | Yamaha Motor Co., Ltd.
Introduces the type MR, shaft motor drive, lightweight, compact, and low cogging model.
01High speed , Long Travel ,up to 4 meters!
The ultimate appeal of linear motor single-axis robots is that there is no critical speed limits such as with ball screws. There is no reduction in the maximum speed even when traveling long distances. Moreover, the maximum stroke is a standard setting of up to 2m on the MR type and to 4m on the MF type. The cycle time in particular for long distance conveyance has been drastically improved.
Linear motor types are more effective in lowering costs when coveying payloads at high speeds, over long distances with greater repeatability.
Systeme feedback is provided by proprietary magnetic scale developed by Yamaha.
The MF series supports double carriers as a standard feature which allows configuring a system with space-saving efficiency.
This arrangement yields lower costs and better tact time as compared to using 2 single axis robot units.
Linear motor type single-axis robots also contain an internal coil inside the table as a drive unit component that eliminates inner dead space and maximizes the stroke. The unit is also bilaterally symmetrical so there is a higher degree of freedom in the robot layout.
Unlike ball screw type robots, there are few sliding and rotating sections so the operation is amazingly quiet. Moreover the coil and magnet do not make contact so there is no wear and the robot can be used for extended periods.
YAMAHA used its own superb magnetic signal detection linear scale technology.
Yamaha's magnetic scale is resistant to dirt and grime and can be used in places partially exposed to grease and cutting oil.
Using semi-absolute specs eliminates the need to make a large return to origin movement after turning on the power (carriage moves a maximum of about 76mm when loading the signals).
The semi-absolute scale acquires the current position by loading signals recorded on the linear scale.
Magnetic signals recorded from the magnetic scale are detected and interpolated to achieve a highly accurate of resolution 1µm.
Making the scale in-house and internalizing it in the robot provides long travel position feedback at reasonable cost.
A fully-closed control system provides constant feedback of the carriage position to attain highly accurate and stable positioning. Backlash is eliminated because there are no mechanical components such as ball screws or drive belts.
All YAMAHA linear motor robots use a stainless steel shutter to prevent dirt and foreign objects from penetrating inside. These shutters are made of tough stainless steel especially designed to withstand an extremely high degree of metal fatigue and made to support long-stroke and highspeed operation.
The PHASER series also supports "multi-carrier" operation that allows using 3 or more carriers on one robot. This "multi-carrier" operation is drastically expanding the current range of applications due to its effect in improving tact time and saving space.
Using dual-drive to simultaneously run 2 axes allows highspeed conveyance over a wide area as well as conveying heavy payloads .Yamaha can provide an optimal control system that matches the linkage rigidity of your robot, such as torque support control or bi-axial positioning control.
11Flat type without flying out the cable support is available for the MF7.
As the main unit is made compact, a flat type that the cable support is flush with the top surface of the table is available as standard for the MF7.
Select this type according to the tool or workpiece shape or the installation method.
Introduces the type MF, providing high power and long stroke using flat motor with core.
Introduces the applications of the linear motor single-axis robots.
Dimensional diagrams and model numbers of the robot cables, cable terminals, and connectors are available.
