New, Three-Phase Linear Drive Does Not Sacrifice Acceleration for Resolution!
San Luis Obispo, CA - The newest addition to the Trust Automation line of Linear Drives is the TA330 linear three-phase servo drive. It is easily configured for three-phase DC brushless servo motors using Hall Effect sensors, three-phase AC brushless motors using external sinusoidal commutation, single-phase DC brushed servo motors in bridged mode, and brushless linear motors. Its flexibility allows motion system designers to easily integrate the latest developments in sinusoidal motor control and its benefits of zero cogging, no torque ripple, and smooth motion, into applications such as, "very high resolution" inspection systems, metrology instruments, and medical applications.
Additionally, the very low electrical noise of the TA330 linear drive makes it ideal for integration in or near systems that have noise sensitive circuitry, such as transducers and sensors. Also the audible noise problems associated with PWM Drives are eliminated.
This powerful 150 Volt, 900 W continuous (2700 W peak) linear drive can be configured to interface with any motion controller. Higher performance systems require a motion controller with the capability to generate the two +/- 10 VDC command signals needed for sinusoidal commutation. The third command signal is generated by the drive to maintain the highest level of precision. The TA330 Drive can be set up to operate in trapezoidal mode using Hall Effect sensors as feedback. The drive also features DTS control which allows the transconductance (torque control) to be changed on-the-fly. An additional benefit is that very high resolution control can be maintained without having to sacrifice power capability.
Additional features: The standard TA330 requires a 24 Volt input to power logic and bias supplies. This standard configuration allows the TA330 to operate with extremely low electrical noise. For applications which are not as sensitive to electrical noise, an optional internal logic and bias supply can be provided which eliminates the need for the external 24 VDC logic supply.
Compact, measuring just 14.9 in. (37.9 mm) X 7.7 (19.5 mm) X 4.7 ( 11.9 mm), it can be used with high inertia mismatched stages and low inductance motors. Integral thermally controlled variable speed forced air cooling, a housing designed to protect against operator injury, easily made connections using ribbon connectors, SMB coaxial connectors, and pluggable-terminal connectors, demonstrate Trust Automation's commitment to operator safety, quiet environment, and ease of integration.
