Motion System Design


Motorized microscope stage

Miniaturized ceramic linear drives from Physik Instrumente (PI) L.P. work with the M-687 motorized microscope XY stage for inverted microscopes.

• Complete system includes a controller, joystick, and software; self-clamping ceramic/ceramic linear motors in the positioner are more compact than electromagnetic motors and provide higher positional stability — once in place, no energy is consumed to hold position (no heat dissipation) • Integrated, 100-nm resolution linear encoders provide direct position feedback to the controller, allowing closed-loop operation with high accuracy • Constant velocity down to 10 microns/sec; travel to 135 × 85 mm; suitable for long exposure imaging, image stitching • Speeds to 120 mm/sec; allows for free rotation of the turret for inverted microscopes



The 3863 CR dc micromotor from Faulhaber (through MICROMO) contains ZHN48 magnet material to produce torque performance of 150 mNm at 8,000 rpm.

• 12, 18, 24, 36, 48 V • Speed controller SC5008 and motion controller MCDC 3006 can be used to control the motor's speed or manage it when deployed as a positioning drive • Low-friction torque and high thermal resistance; can be assembled with a wide range of gearheads and encoders up to 1,024 resolution

SCR-rated motors

Ohio Electric Motors' custom designed, SCR-rated dc motors are compatible with full wave, phase type, or pulse-width-modulated SCR controllers.

• NEMA frames 48, 56, 143, 145, and 184 with an output range from 1/4 to 3 hp • 1,750 to 2,500 rpm and 90 to 180 Vdc • Suitable for machine tools, electric vehicles, and servomotors; NEMA-rated magnet wire with Class H Insulation, polyester varnish impregnated armatures, dynamic balancing to reduce vibrations, oversized and sealed ball bearings with high temperature grease • TENV/TEBC/TEFC, low-loss steel laminations • External brush access, excellent heat dissipation, UL and CSA Listing and optional anti-rust, zinc coating, or private labeling


90-mm flat motor

The brushless dc EC90 ultraslim motor from maxon precision motors inc. is now equipped with a MILE (maxon's Inductive Little Encoder), possibly the world's smallest inductive rotary encoder.

• Detects high-frequency inductivity, which generates eddy current in an electrically conducting target • Resolving up to 3,200 impulses/turn, resistance to dust or oil vapor • Insensitive to interference pulses as from PWM controllers or motor magnets • 517 mNm output


Hygienic servomotors

The Kollmorgen W Series IP69K-sealed hygienic servomotors feature an all-stainless-steel, round housing design for long life and reliable operation in harsh washdown applications.

• Venting system eliminates need to supply compressed air to the motor, and a 3 and 6-m standard flying lead option eliminates the need for intermediate cables • High-grade stainless steel for all external and internal metal components, food-grade bearing grease, a food-grade shaft seal, and a laser-etched nameplate • 16 frame/stack combinations deliver 80-Nm continuous torque and 390-Nm peak torque at speeds to 7,500 rpm


Integrated vertical and rotation stage

The ZVR from Newport Corp. is suitable for semiconductor wafer positioning, metrology, inspection, and repair.

• Also useful in LED production and applications such as 3D scanning, digitizing models, and validation; improved cantilevered load capacity • Significantly lower cross-talk than earlier designs, low mass, high natural frequency • Three-point base — for stability — with a stepper-motor-driven 10-mm Z stage; stainless-steel rotation stage features smooth operation utilizing stainless steel ball bearings • Aperture through the center of the stage simplifies electrical cable and vacuum-chuck cable/hose management


Tiny stepper motor
