Use the extended screws for mounting but do not adjust them. Take normal vacuum precautions, avoid creating trapped volumes when mounting the motor and obstruct as few as possible of the pumping holes in the end faces. The location spigot projecting from the f...

The preferred method of coupling a load to the shaft is by a setscrew or collet fixing. AML do not recommend users modify shafts.

Motors are supplied pre-baked to 200 °C in 1 x 10-6 mbar pressure for 24 hours and vented with dry Nitrogen before vacuum packaging. They may still adsorb water in storage and handling so a 24-hour bake by an AML stepper motor drive, with an adequate pump is r...

These motors are specifically designed for use in conjunction with AML stepper motor drives current-regulated switch-mode drive. If another drive is used it must be a bipolar 2-phase drive and capable of providing a selection of well-regulated currents of less...

All AML motors are provided with a K-type Thermocouple (NiCr-Ni) embedded between adjacent windings as standard, oralternatively, the PT100 temperature sensor option. The drive current must be removed when the indicated temperature of the windings reaches 190 ...

The lead-out wires are self-coloured polyimide film-wrapped, silver-plated OFHC copper and each is fitted with a 1.5 mm crimp socket terminal. They are supplied fitted with UHV compatible coloured glass beads for identification. Lead-out wires are supplied 1.5...

Motor wiring Overview Connecting motors inside a vacuum chamber to the SMD4 comprises two tasks: Wiring the motor to a vacuum feedthrough installed in the chamber wall. Wiring the vacuum feedthrough to the SMD4. AML supply vacuum feedthroughs,...

It will be necessary to cut off the crimp terminals fitted to the leads and re-strip them. Standard motors are fitted with Polyimide film-wrapped leads: radiation-hard motors are fitted with Polyimide lacquer-coated leads. Polyimide is strong, flexible and ab...

There is a 50% probability that the direction of rotation will be reversed from the desired or conventional sense. To reverse the direction, exchange the connections to one of the phases. Check that the drive, wiring and motor combination work properly before...

If the motor rotates at the wrong speed, frequently changes direction, or has low torque this is probably due to one of the phase connections being open circuit. If the drive indicates that the motor temperature exceeds 190 °C when the motor is not hot, then ...

It is recommended that motors and mechanisms are operated in air during early commissioning. This has the advantage that more cooling is available and that the operator can see and hear that the motor is stepping. Temperature Rise and Run Times The maxim...

Most AML products have a C# API available to allow easy integration of the product into your own application, without having to write an API yourself. The C# APIs provide an easy way to access all aspects of configuration and control of the product. Using the...
