• Reduced wiring
• Single package saves space

Unitized DC motor and control.

A series of brushless DC motor products has been introduced. The INTEGRAmotor integrated control circuit simplifies installation and minimizes any EMI problems. The single plug-in connector for power and logic reduces wiring cost and design time. There are inputs for run, brake, speed and direction, and the motor is current-limited against overloads. Tach output is 12 pulse/revolution, and dynamic braking provides quick stops. The motors are offered in direct drive (shown), parallel shaft with an integral gear reducer, or right angle output through a worm gear reducer. The two basic direct drive motors are offered as 1/16 or 1/8 HP output, with a speed range of 100 to 2500 rpm. Bodine Electric Co, Chicago, IL. http://www.1rs.com/011df-421

Repackaged integrated servo. The latest of the SmartMotor series moves the control board from the end of the motor and onto the top, for a very compact package. The company also introduced the SM2315 device at a cost low enough to compete with many stepper systems. The package has a patented barrier material to protect the electronics from the motor's heat, and can deliver up to 30 oz-in. of continuous torque and speeds up to 10,000 RPM.

Small AC servos. The slim and cylindrical "W" series motors have rated speed up to 3000 RPM and maximum speeds of up to 5000 RPM, with a range of 30W to 5.5 kW. An integrated keypad with a 5-digit display on the drive can be used for programming parameters and monitoring drive status and alarms. Built-in auto-tuning provides fast start-ups and installations, and high resolution feedback allows for smooth control at low RPM.

Sine encoder option on servomotor. The PLATINUM DDL (Direct Drive Linear) line of frameless, permanent magnet brushless servomotors are now offered with a high-resolution sine encoder option. This type of encoder improves velocity control and repeatability, increases system stiffness, and reduces position dither. It also increases feedback accuracy to allow accurate positioning of the load. The motors have continuous torque ratings from 13.6 to 3513.0 lb/ft. Kollmorgen, Radford, VA.

CAM controller. Designed for use with steppers and digital input servo motors, the ECM010-Electronic CAM Controller increases the flexibility of motion control systems. The compact single axis controller can be connected to 15 other controllers to coordinate complex multi-axis manufacturing and testing operations. The controller has onboard data storage for 16 CAM patterns, as well as programs and system parameters. NYDEN Corp, San Jose, CA. http://www.1rs.com/011df-425

Space-rated motors. Two-phase hybrid stepper motors, three-phase brushless motors, feedback devices and mechanical assemblies have been developed by this company to suit requirements for missions into outer space . The components are designed to tolerate vacuums of 10^-8 to 10^-12 torr, launch vibrations, radiation and ionized particles, load changes from 25+ G's during launch to orbital weightlessness, thermal shock and cryogenic temperatures.

Control chip. The PCL-6045 motion control chip offers 4-axis independent control in a 176-pin QFP. It supports linear or circulation interpolation, or a combination of the two. Positioning and speed parameters can be changed on the fly, and the chip also includes damping oscillation control, a pre-buffer for subsequent profile, automatic correction of operating speed, backlash correction, and out-of-step detection. Maximum output speed is 6.5 Mpps. Nippon Pulse Motor Co, Ltd, Radford, VA.

Hybrid stepping motors. Two 1.8 deg full-step angle stepping motors are designed for use in robotics, production line machinery, and other instrumentation applications. Identified as the D34D62-424 Series, both 108mm dia., 8-lead motors operate at 200 steps per revolution and provide a holding torque of 781 oz-in. They can be run clockwise or counter-clockwise, depending on input, and single or double shafts may be specified. Stock Drive Products, New Hyde Park, NY. http://www.1rs.com/011df-428

Multiplexing system. A combination of advanced hardware and software provide control of multiple motors from a single variable frequency drive. The system can be applied to multi-pump or multi-fan arrays where system flow or pressure can be maintained by a combination of constant and variable speed operation. By switching different AC motors between VFD and line power as loads change, the Multiplexing System reduces wear on pumps and motors.
