Encoders

CUI (Tualatin, OR) offers the AMT31 modular encoder series that generates standard U/V/W commutation signals for vectoring current to brushless motors. Positional information is generated using a patented capacitive code generation system coupled with a proprietary ASIC. The encoder is designed for use in brushless dc motor applications subject to vibration and contaminants such as dust, dirt, and oil that typically stop optical encoders from working effectively. They deliver accuracy of ±12 arcmin (±0.2 mechanical degrees). Twenty programmable resolutions are available with a range of 48 to 4096 PPR.

AC Drive

The VACON® 100 FLOW from VACON (Milwaukee, WI) is an AC drive designed to improve flow control for multi-pump applications in which several pumps are used in place of a single one. The drive offers control of flow and pressure for a maximum of eight pumps (or fans) without the need for an external controller — communication between drives is provided by integrated RS-485. It is equipped with built-in Ethernet as standard, eliminating additional options or gateways needed to communicate with process automation. The drive offers three multi-pump control solutions: single-drive multi-pump, multi-drive multi-master, and multi-drive multi-follower.

Table Motors

Siemens AG (Munich, Germany) offers the Simotics DP motors based on the 1LE1 motor platform. The ventilated roller table motors are designed for applications in the steel industry where they must meet requirements for vibration and shock according to Class 3M4. Versions of the motors are optimized for use with converters of the Sinamics S120 series and, as integrated drive systems, contribute to reliable and efficient operation. The motor design has been tested in accordance with to DIN EN60721-3-3. They are available in 4- and 6-pole designs with shaft heights from 112 to 280 mm, and in the torque range from 20 to 578 Nm. The series comprises not only mains powered motors, but also versions optimized for converter operation with special insulation systems. When used together with the Sinamics S120 drive system, these motors form an integrated drive system.

Linear Actuators

Parker’s Electromechanical Automation Division (Irwin, PA) released the High Moment Rodless (HMR) electromechanical linear actuator series that features five different frame sizes, two different drive train options, an IP54 protective cover option, and multiple motor mounting, carriage, and sensor options. The actuators integrate externally accessible lubrication fittings into the carriage that evenly disperse lubricant across the bearing trucks and ball nut. Two options for chassis profiles are available: basic or reinforced.

Rod-Style Actuator

The RSA-HT high-force rod-style actuator from Tolomatic (Hamel, MN) can also be considered as a replacement for hydraulic applications and offers maximum force capabilities of 12,900 lbf (57.38kN). Features include an IP67 option, standard purge/breather port, and a lubrication system. The actuator includes a grease zerk for lubrication without disassembly. The purge/breather port allows positive pressure to be applied to the actuator to help keep contaminants out, and functions as a breather port in high-speed applications where internal pressures may exert additional forces on the actuator if sealed.

Controller Systems

Velmex (Bloomfield, NY) offers VXM controller systems for power systems that drive motorized products including slides and rotary tables. The controller is a 2-phase, unipolar stepper motor controller that can drive and control precise movements, multi-axis, and velocity. The system is capable of controlling up to four motors, one motor at a time. Two motors can be controlled simultaneously for coordinated motion. Features include an intuitive, comprehensive command instruction set; single-chip microcontroller that digitally controls the motor phase switching and all other interface functions; elimination of noise-sensitive step and direction translation circuitry; and resonance-free motor torque from modulated current control.
