Sensorless Motor Driver

Koford Engineering (Winchester, OH) offers the S24V30A sensorless motor driver with 37 kHz pwm frequency for use with standalone, digital, or analog operation. The drive has no minimum inductance and will operate slotless or ironless brushless motors without the need for inductors. The drives can be operated in standalone mode with a speed pot or with an 0-5V analog input or a 5V pwm input from a microcontroller or microprocessor. The motor is turned off for an PW input between 0 and .5 Volts. Once power supply, motor, and speed pot (if used) are connected, the motor can be operated without the need for any adjustments, setup, or programming.

Load Carrier

Amacoil (Aston, PA) has introduced a linear bearing slide load carrier to enhance the load carrying efficiency of Uhing traverse drives and to prevent them from slipping. The load carrier protects the rolling ring bearings from undue wear by assuring that weight and radial forces are not transmitted to the shaft-bearing interface. Supported by end supports and guide rails, and riding on linear bearings, the load carrier accepts the full force of any payload attached to the Uhing traverse. Two yokes extend down from the load carrier. The traverse pushes against the yokes to move the load linearly. The yokes are not screwed or bolted to the traverse, so no forces are placed on the traverse other than the lateral resistance to movement of the load carrier.

Pump Vanes/Rotors/End Plates

Metallized Carbon Corp. (Ossining NY) offers custom vanes, rotors, and end plates for use in rotary vane pumps pumping both liquids and gases. The carbongraphite components provide lubrication in most environments, and are suited for pumping liquids with poor lubricating qualities, strong chemicals that attack metals, and to pump air, vacuum, combustion products, and gasoline vapors. The materials are chemically resistant, and are compatible with FDA food and beverage regulations. They have a low wear rate running in both gas atmospheres and low-viscosity liquids.

Reducing Machine Controller Design and Deployment

Machine design and deployment requires integration of various technologies such as controls, mechanics, vision, lasers, data acquisition, and software, to mention only a few. These mechatronic solutions usually target a specific purpose such as part manufacturing, marking, packaging, etc. Often the controller is a key focus in the design because it must connect and coordinate all of the processes on the machine. Using separate programmable logic controllers (PLCs) and motion controllers necessitates integration, which is costly and time-consuming. Using a single controller for the machine eliminates the need for integration and shortens design and deployment time and cost.
