In this project a servo (position) controller that is able to receive commands via a Controller Area Network (CAN) is presented. Additionally, the board was developed to be as generally usable as possible in the sense that if the DC motor to be controlled does not have a rotary encoder, then a contactless magnetic rotary encoder (CMRE) module can be plugged into the board (via two SIL connector...

The new Lcica RM 2165 automatic, heavy-duty microtome has an advanced step motor that permits an exact specimen feed and reproducible sectioning results. Features include 70 mm vertical stroke length, unique step trim function, and programmable specimen retraction. Technical features include a handwheel rocking sectioning mode; the motorized specimen feed can be linked to change the handwheel t...

All moving objects possess six degrees of freedom – three linear and three rotary. The task of a linear motion guideway is to eliminate, as closely as possible, five of these degrees of freedom, leaving a single rotary or linear axis of motion. Air bearings are the purest and highest performance means of defining linear or rotary motion, and have substantial advantages over conventional mechani...

In this paper, we will demonstrate a family of novel Rotary Inchworm motors using four gap-closing actuators (GCA). Design issues, fabrication process, and expected operation of several rotary motors will be described. The motor is to be batch fabricated using Seth Holler’s Silicon-on-Insulator (SOI) plus hinges process. An output torque of the order of nN-m with a torque density in the range o...

In the paper a switched reluctance rotary-linear motor is proposed. It is mechanically robust, simple to construct and easy to operate also in hostile working environment. The stator has a modular design compound of three correctly shifted usual 16 poles SRM stators. The rotor is constructed of several common 12 poles SRM rotor stacks. The motor is able to ensure both rotating and linear moveme...

introduction: to compare the cleaning effectiveness of k3 and race niti rotary systems with k-flexo file instruments during the preparation of curved canals in extracted human teeth. materials and methods: a total of 50 root canals of mandibular and maxillary molars with curvatures ranging between 25º and 35 º were divided in three groups of 15 each and 5 as negative control groups. canals were...
