Motion Control

Motion Module

Mitsubishi Electric (Vernon Hills, IL) has introduced the QD77MS Simple Motion Module that simplifies programming of complex motion profiles. Programming and setup of both PLC and motion control are performed using a single software program. Controller compatibility assures smooth migration to technology platforms using tools that offer motion project diversion and project recycling capability. Drive compatibility allows the use of either existing or newer servo amplifiers for actuation control. Available with 2, 4, or 16 input/output axes, the module is designed for use with the iQ automation and control platform.

Motor Controls

Cerus Industrial (Hillsboro, OR) offers the BAS (Building Automation Starter) motor controls that incorporate the company’s patentpending Smartstart™ Control Module for integration with digital controls. The starters accept dry voltage inputs (wide range 12-250VAC) for activation by control systems without interposing relays. Other control options include auto run, fireman’s override, fault, proof of flow (detects loss of load), and SmartStart predictive calibration (fault alarm). Integrated LED pilot lights and Hand/Off/Auto keypad are standard.

Speed Reducers

Boston Gear (Charlotte, NC) offers the 700 Series speed reducers for heavy-duty conveyor systems. The 752 size worm gear speed reducers feature hollow output shafts in 5.25" center distance. Output torque ranges up to 12,250 lb.ft. Six new bore sizes are offered ranging from 2" to 3-7/16". Double reduction ratios are also available. The internal worm is specially ground for lower heat generation.

Linear Drives

Amacoil (Aston, PA) offers Uhing Model RG linear drives with a manual pitch control that permits a 10:1 adjustment of the linear pitch of the drive unit. Each of the 17 drive units has a specific maximum linear pitch — the linear distance the drive will move on the shaft per one revolution of the shaft. The pitch control lets users turn the pitch down in 0.01 increments across 100 discrete settings.

Dual-Axis Inclinometers

The Fredericks Company (Huntingdon Valley, PA) offers a microprocessor-based analog output dual-axis inclinometer with RS-232 communications, and a dual-axis inclinometer with RS-485 communications. They are designed to interface with all types of instrumentation and equipment, offer an angle range of ±60º in two axes (x and y), 0.2 arc-minute resolution (0.003 degrees), and ±0.1-degree repeatability. Custom angle ranges are available. Typical applications include crane boom angle measurement, robotic controls, satellite dish alignment, solar panel position and elevation control, wheel alignment systems, alarm system activation, machine tool leveling, and medical equipment positioning and monitoring.

Slotless Motors

Nanotec Electronic U.S. (Medford, MA) offers the DS16 and DS28 slotless BLDC motors in two models in Nema 6 (16 mm) and Nema 11 (28 mm) sizes. Since there is no iron core, the inductivity of the motor is very low and the current increases very quickly in the windings. In slow operation, the lacking torque tripple has a positive effect. Since the magnetic field is not reinforced on the pole shoes as with standard BLDC motors, there is no cogging torque. The DS16 slotless BLDC motor offers an output of 24 Watts at 25,000 rpm; the speed of the DS28 model is 14,000 rpm at 75 Watts.

Leveling Mounts

The V10Z44MCM Series of 3-in-1 leveling mounts from Advanced Antivibration Com - ponents (New Hyde Park, NY) dampens shock and vibration, provides leveling, and offers position mobility for packaging machinery applications. They incorporate a moveable mount in which the rubber mount is incorporated with a rotating ball. The maximum recommended load of the two isolators ranges from 200 kgf to 600 kgf (441 lbf to 1323 lbf). The diameter of the unit base ranges from 100 mm to 140 mm (3.9" to 5.5").
