TA333 LINEAR DRIVE FOR BRUSH SERVO MOTORS

Consistent Linear Voltage Output with no Voltage Deadband around Zero Point. The Trust Automation TA333 Linear Drive is another fourth generation drive in Trust Automation Inc.’s continually expanding product line. This linear three-phase servo motor drive, as all Trust Automation Linear drives, is a true class AB amplifier and is the most up to date technology in the industry for sinusoidal motor control. Linear sinusoidal commutation of three-phase brushless servo motors eliminates the familiar cogging and torque-ripple problems that plague most trapezoidal digital drives. For ultra low noise applications, (i.e. transducers, sensors, etc.), the TA333 provides an optional external 24V Input which replaces the internal bias switching supply, further reducing electrical noise. The TA333 is a highly configurable device with four common configuration modes. The TA333 will drive one brushless motor using external sinusoidal commutation. It can also use Hall Effect sensor feedback for smooth internally commutated trapezoidal operation. The TA333 also supports one or two brush or voice coil type motors as well as driving two coil stepper motors under sinusoidal control.
