Shaft motor: high-speed reciprocating motion demo
This is a high-speed reciprocating motion demonstration using a linear shaft motor. The shaft motor is being operated at the frequency that can be driven for each motion stroke.
Shaft motor: pressure control unit
High precision pressure control is available from very low pressure. The mechanism at the lower stage is being aligned in high resolution using a small DD motor.
Alignment stage / UVW stage
High precision control alignment stage using four shaft motors. X and Y-axis linear motions and θ motions are available.
LINEARSTEP [PFL20] Dispensing demo
This is a dispensing demonstration that uses a linear step (direct-drive type stepping motor) [PFL20]. Diameter of PFL20 is 20 mm, which is the smallest in LINEARSTEP series.
High-speed serial communication system: Motoinnet 64-axis control
The broadcast communication function of Motionnet allows simultaneous start with 64 axes and zero delay time.
Shaft motor: Pneumatic hybrid precision pressurization control
Pressurization from very low pressure to high pressure can be controlled with high precision.
It is a hybrid high-precision pressurization control device with an unprecedented linear shaft motor and pneumatic servo.
Shaft motor: 4-axis multi-drive
Linear shaft motors are linear brushless motors that enable high-speed, high-efficiency, and high-precision positioning controls. In the movie, four forcers on one single shaft are being controlled independently.
Direct-drive type stepping motor: LINEARSTEP dispensing demo
Linear step is a direct-drive type stepping motor that utilizes the structure of a conventional stepping motor.
Rotational motion is converted into linear motion by a shaft with male screw and a rotor with female screw integrated.
Shaft Motor: Single-axis slider robot- NPROBO
NPROBO is a linear servo actuator capable of high speed, high efficiency and high precision positioning controls.
The principle of movement consists of a shaft with a cylindrical magnet in a stainless steel pipe and a coil part of a black aluminum casing that surrounds the shaft. When current is passed through the coil, a magnetic field is generated to drive linearly.
Shaft motor configuration example
This is an example of shaft motor assembly.
Necessary parts are the shaft motor unit (shaft and forcer), linear guides, linear encoders, mounting brackets, cable carriers, etc. By fixing the shaft and forcer to the mechanism with a bracket, etc., the airgap between the shaft and the forcer is maintained.
