Servo controller/driver saves energy while accelerating robotics
A single-axis controller / driver module by Trinamic integrates motion control to speed transfer time in two-phase bipolar stepper motors. The TMCM-1321 also reduces solution size and saves energy, says the company.
It is claimed to be the smallest and lowest-power single-axis servo controller/driver module with integrated motion control. It enables two-phase bipolar stepper motors in robotics and automation equipment to optimise the speed and synchronisation of axes for quicker throughput while also reducing power loss by 75 per cent, says Trinamic. An on-board magnetic encoder and digital inputs for an optical encoder simplify servo control. At 784 mm², the TMCM-1321 is claimed to be more than three times smaller than similar stepper motors.
The TMCM-1321 module features linear ramping, Trinamic SixPoint ramping, as well as an S-shaped ramping to speed effective transfer time. Trinamic’s closed-loop technology uses direct feedback to automatically reduce power loss by 75 per cent. There is also an RS-485 interface and Trinamic’s integrated development environment, claimed to further simplify design and reduces stepper motor size.
In addition to reduced power, the TMCM-1321 improves effective transfer time by implementing the ramping profile that matches the application’s demands, explains Trinamic.
