Linear stepper motor actuator with air/ball bearings
Linear Stepper Motor Actuator "Plug-and-Play"
Closed Loop Linear Stepper Motor Linear ServoStep™
IntelLiDrives linear stepper motor actuator system is a complete linear positioning actuator has the motor, bearings and feedback device integrated into one compact package.
Linear stepping motors are ideal for positioning applications with light to medium payloads. They can be used at speeds up to 60 in/sec and strokes up to 144" (longer strokes can be achieved with modular platens). Linear stepping motors are capable of very precise positioning and velocity controls when used with micro-stepping drives and indexers.
Series BB linear stepper motor consists of two parts: |
|
|
|
moving forcer assembly incorporates electromagnetic motoring modules and mechanical roller bearings. The bearings are designed to support customer payload and to maintain air gap required for motor operation. Both side and bottom bearings are magnetically preloaded against the platen and no user adjustments are required to set up and to maintain the air gap . Forcer can be supplied with D-sub connector or cable track adapter with high-flex cable to connect to drive electronics. Multiple forcers can be installed and independently operated on a single platen. |
|
|
long stationary platen is a precision ground hardened stainless steel bar with epoxy filled slotted grooves. The platen is passive and does not contain any magnetic material. The platen length is a function of stroke. Long platens can be supplied as a single bar or in modular sections that can be interlocked with each other to form very long continuous platen. Platens manufactured in precision and standard grades with running parallelism and flatness of 10 and 5 microns. |

IntelLiDrives linear stepper motor compatible with the same full step or micro-stepping electronics used with rotary stepping motors. When operating with micro-stepping drives or indexers very fine resolutions are achievable. With 256 micro-step/step drivers, the micro-step resolution will be 0.010"[0.25mm]/256= 0.00004"[1 micron].
For applications requiring ultra precise positioning and dynamic performance IntelLiDrives linear stepper motor can be supplied with tape-less IntelLiCoder feedback for closed loop brushless Linear ServoStep operation. |
