GAO Embedded (www.GAOEmbedded.com) is proud to introduce the new low-voltage servo motor driver intended for high-performance DMC systems. Based on the TMS320F2812 DSP from Texas Instruments (www.ti.com), the servo motor driver is part of a fast and reliable servo motor driver solution that comprises three parts: the LVD (driver part), the IB2812 (interface part) and the EVM2812 board (DSP part). The evaluation board connects with one or two DC brush or brushless servo motors, AC asynchronous motors, AC permanent-magnet synchronous stepper motors or servo motors to create a digital servo-motion control system.
The MCK2812 LV (Low Voltage) Servo motor Driver uses a 24V DC to 80V DC power supply that offers a maximum peak value current of 10A and an output power of up to 400W. It offers an on-board 30W rebooting power switch to supply large current safely; on-board precise resistors to carry out a three-phase current sampling and ensure accuracy; and on-board filter to minimize EMI interference based on the FCC-15 standard. The servo motor driver evaluation board also features a special driving chip and a 20A/200V MOSFET tube to protect against over-voltage, over-current, over-heating and under-voltage; an input interface for Hall sensor signal and incremental photoelectric encoder signal; and a feedback interface for current/velocity/position feedback loop. The evaluation board also provides a PWM frequency of up to 40kHz.
Other features of the low-voltage servo motor driver include motor control source code for DC brush and brushless servo motor, AC asynchronous motor and AC permanent magnet servo motor SVPWM and SPWM, a hardware user manual, as well as hardware schematics.
