TSM23X3B - NEMA 23 StepSERVO™ Integrated Motor with TruCount™ Encoder

The TSM23X3B StepSERVO™ Integrated Motor is a drive+encoder+motor unit, fusing a NEMA 23 step motor and a servo drive into a single device. Power to the drive, located at the rear of the motor, must be supplied by an external DC supply. See Recommended Products below for compatible 48 volt DC power supplies.

StepSERVO™ Closed-Loop Stepper Technology

StepSERVO technology combines the high torque capabilities of a step motor with the closed loop dynamic control of a servo system. The result is a highly configurable all-in-one motion control solution that operates quietly and efficiently, requiring only the minimum amount of current to maintain commanded position and velocity. Boost (or peak) torque that is higher than the rated holding torque increases the limits of acceleration, leading to faster cycle times. StepSERVO integrated motors can be applied in systems where a traditional stepper motor would not be capable of achieving the high accuracy required.

TruCount™ Multi-Turn Absolute Encoder Technology

TruCount™ absolute encoders provide the ultimate in hassle-free positioning of rotary and linear axes. TruCount encoders are multi-turn, absolute encoders that don’t require batteries or external power to track encoder position while the motor is powered off. There are no mechanical gears in TruCount encoders. The encoders make use of a novel energy harvesting technique that continues to track motor position when the motor is powered off. Any amount of displacement in the shaft causes enough energy to be created for the motor to continue tracking its absolute position. It is an extremely effective approach to multi-turn, absolute position tracking. Utilizing multi-turn, absolute encoders in motion control applications reduces downtime by shortening machine power up sequences and eliminates the need for homing runs after power cycles and emergency stops (e-stops).
