High Speed Reversing Drive from Force Control Industries

Fairfield, OH – A new high-speed reversing drive from Force Control Industries uses dual clutches to provide rapid reversing without undo strain on the motor or drive system. Unlike traditional reversing applications where the motor must accelerate in the forward direction, stop, then accelerate in the opposite direction and then stop again, the dual clutch Posidyne® eliminates stopping, starting, and accelerating the motor. 

In the High Speed Reversing Drive (HSRvD) the input to the two clutches rotate in opposite directions. Force Control High Speed Reversing Drives are ideal for higher horsepower applications (up to 75 hp) that require reversing often, such as automotive production machines, machine tools, mineral processing, loading machines, and many more.

Several versions are available to suit many industrial applications. In the Type II HSRvD one motor rotating in the forward direction is connected through a primary clutch and a second motor running in a reverse direction is connected through the secondary clutch. By actuating the proper clutch and brake, the reversing is handled within the Posidyne® while the motor runs continuously.

In the Type I HSRvD there is only one input motor. The input to the two clutches rotates in opposite direction by means of a jack shaft through a reversing gear set.

The Force Control High Speed Reversing Drive uses less power than traditional start/stop systems, generating much less motor heat. Traditional systems reverse the drive motor each cycle, so the major inertia load is typically the motor rotor itself, degrading the motor’s service life. With Force Control, the motor runs continuously while the reversing is accomplished with the Posidyne® resulting in significantly longer service life for motors.

Oil Shear Technology is the reason that brakes by Force Control do not need constant maintenance, adjustment, disc replacement, and last up to 10 times longer than standard dry friction brakes. Oil Shear Technology is the function of a boundary layer of transmission fluid in shear between the friction disc and drive plate. As the parts come together the fluid under shear will transmit torque between the two parts as well as absorb heat. This eliminates direct contact of the friction discs and drive plates during high speed slip. Heat from the friction surface is dissipated as the fluid circulates to the housing.

Borries integrates high-speed drives in its markers

Borries Marking Systems (www.borries.com) has announced the release of the latest high-speed motor drives integrated in its programmable dot peen and scribe marking machines. These drives replace the more complex and expensive servo drive systems, which are current alternative for marking situations.

Borries latest markers feature an upgraded, high-speed stepper motor drive system that reduces cycle time in half-or more.

The drives were originally developed in response to the demands of the automotive industry for lower machine cycle times but faster production rates, as manifested by automotive stamping plants, where the stamping plants deliver 12 characters in three seconds at a speed of 5 mm.

Aside from the new systems, which are capable of increasing the throughput and reducing the cycle time, the company also provides retrofit packages for existing devices.

With the use of higher speed drives, the devices can be installed as retrofit kits either at the Borries factory or in the field. This gives users an affordable solution for optimizing marking speeds without the need of acquiring a new device.

Borries’ high-speed drives can be translated into several marking technologies: Stylus Marking, which utilizes fast-vibrating needle technology to produce minimal force on three-dimensional material; Scribe Marking, which is ideal in almost all deformable, three-dimensional configuration and delivers continuous-line mark that are easily-readable; Dot Matrix Marking, which is similar to Stylus Marking and Scribe Marking, but provides a visible dotted appearance; and DataMatrix Marking, which uses the same tool with the dot matrix and provides 2D codes (ECC 200 standard) that are camera-legible.

These high-speed drives are offered in the company’s programmable dot peen and scribe machines portfolio.

Next-generation ABB Industrial Drive Module Expands to 600 HP

New Berlin, Wis. – ABB’s new drive module ACS850 is now available and UL listed up to 600 HP.

The ACS850 features on-board safe-torque-off, a removable memory block, intelligent user interface with a series of assistant wizards, a built-in energy saving calculator, and modular hardware and software. It also includes an advanced adaptation of ABB’s unique motor-control platform, Direct Torque Control (DTC).

These industrial drive modules are designed for industrial machinery and applications such as extruders, cranes, mixers, web handling and converting, in the power range of 1.5 to 600hp at 480VAC.

An integrated Safe Torque Off (STO) feature removes the torque from the motor shaft. This safety feature conforms to the requirements of SIL 3 / IEC 61508, Cat 4/EN 954-1, EN ISO 13849-1:PL e. There are also solutions available for Safe Stop 1(SS1), Safe Limited Speed (SLS), Safe Brake Control (SBC), Safe Speed Monitor (SSM) and Safe Direction (SDI).

A removable memory block increases the flexibility of the drive and provides for easy maintenance. The memory block stores the complete firmware, plus all user settings and motor data. If the drive is replaced, it can be re-commissioned without any special knowledge via simply plugging the memory block into the new drive

The intelligent user interface with advanced assistants significantly decreases the need to refer to manuals, while saving time in commissioning.

The ACS850 is engineered to work with the latest generation of ABB high-speed serial interface modules. Supported protocols include DeviceNet, Modbus RTU, Profibus, and CANopen. Before the end of 2009, the ACS850 also will support Ethernet/IP and Modbus-TCP.

The maintenance and diagnostics assistants help keep the process up and running and, in cases of disturbance, minimize the downtime by giving advance warning of maintenance needs of the drive, motor or related components.

These compact drive modules, with protection class IP20 (G frame IP00), are optimized for installation into cabinets. The smallest module width is only 3.7in. The modules can be installed side-by-side, which saves space as more drives can be placed in the same cabinet.
