US Patent:

6803681, Oct 12, 2004

Filed:

Jun 19, 2001

Appl. No.:

09/884410

Inventors:

Mustansir Faizullabhoy - Stony Brook NY
Anwar Chitayat - Fort Salonga NY
Joseph Cardamone - Shirley NY

Assignee:

Anorad Corporation - Shirley NY

International Classification:

H02K 4100

US Classification:

310 12, 318135

Abstract:

A path module for a linear motor system includes a controller coupled to one or more amplifiers that are operative to control associated windings in the module. The controller receives control information via a communications link. The controller controls the amplifier based on the received control information so as to selectively energize the associated windings in the module. In one aspect, a plurality of such modules may be connected together to form a path along which one or more stages are moveable according to energization of the windings in the path.

Assignee:

Anorad Corporation - Shirley NY

International Classification:

H02K041/00

US Classification:

310 12, 318135

Abstract:

A wireless encoder system facilitates operation and control of a motor, such as linear motor. The system includes an encoder sensor moveable with a first part of the motor. The encoder sensor is operative to sense movement of the first part relative the second part and provide an encoder signal having an electrical characteristic indicative of the sensed movement. A transmitter, which is associated with the encoder sensor, is operative to transmit a wireless transmitter signal based on the encoder signal. A remote receiver that receives the wireless transmitter signal thus may determine position and/or movement of the first part of the motor relative to a second part of the motor.
