Torque Module produces output rotation in either direction.

Press Release Summary:



MTC Motorized Torque Control system is available in models from 50 to 200 kN. It has servo motor, encoder, torque transducer, output shaft, and electronic controller. Signature analysis technology monitors force and position during test and creates electronic signature. System compares each subsequent test to signature. Tests can be conducted during assembly operation.

Promess Expands Range of Its Motorized Torque Control (MTC) System for Test and Assembly Equipment Builders and End Users


BRIGHTON, Mich., June 24, 2002 -- Promess, Inc., a manufacturer of in-process sensing and measuring devices as well as a full line of closed-loop, CNC, electrical/mechanical assembly presses, has expanded its line of new motorized torque control (MTC) systems from two to five sizes; the product range now encompasses from 50 to 200 Kn.

The MTC system, which features built-in angular sensing and feedback capabilities, is designed for use by test and assembly equipment builders and end users in such applications as automotive steering and drive train component testing and assembly, manual window crank final testing, seat testing, bearing pre-load, and torque-to-turn testing.

The complete turnkey torque system consists of 1) a torque module which contains a servo motor, encoder, torque transducer, and output shaft; and, 2) a Promess EMAC electronic controller/monitor.

The torque module can produce output rotation in either direction. The integral angular encoder provides shaft-angle feedback to the control. Mechanical overload stops are provided to protect the transducer.

Offered in both base-plate and flange-mount configurations, the Promess torque module replaces the traditional inline motor/transducer torque sensing system.

Promess' EMAC is an easily-programmed, fully-integrated, multi-axis motion controller and monitoring system that can accept both digital and analog signal inputs and provide both dedicated and user-definable output.

EMAC controls are easily networked, and are equipped with internal storage for multiple part and/or operation programs. They feature Windows-based software, and make use of Promess's exclusive signature analysis technology which makes the system particularly well-suited for assembly and torque monitoring applications.

Signature analysis technology monitors both force and position during a process and creates an electronic signature of a successful operation. By comparing each subsequent operation to the signature, and setting upper and lower tolerance limits, production of good assemblies can be assured without the need for subsequent inspection.

The Promess torque module and EMAC monitors both torque and position during the operation, and plots both to create an accurate, repeatable signature. The exact shape of the signature also provides important information about the individual parts being assembled, which can be used as input to control strategies for other processes.

For example, parts that are too soft or too hard (bi-metals) will produce a distinct change in the signature, as will parts with out of tolerance assembly details such as hole or shaft diameters.

Promess is an 18-year-old firm that develops, manufactures, and markets its family of sensing devices, electronics, assembly presses and test systems on a global basis.
