Small drives, big power
Frequency up to 100 KHz.
The company says the unit, about the size of a smartphone and weighing just 250 g, is one of the smallest drives available.
For stepper motors, control is achieved via a closed loop commutation that delivers servo-like performance.
With a 12-A peak current and a switching frequency of up to 100 KHz, the drive’s high PWM switching frequency, field oriented control and space-vector modulation operates low inductance motors while minimizing current ripple and eliminating acoustic noise.
Separate logic and bus power supplies make motor power-off safe while maintaining the drive state and fast restart.
Servotronix, a manufacturer of motion control equipment based in Isreal, says the LVD has been qualified by Bosch Rexroth to operate with the IndraMotion Control models, MLC motion logic control, MLD drive-integrated motion control and MTX CNC platform.
