PMM integrated servo motor

PMM40 Integrated low voltage servo motor

PMM40 introduction
PMM series integrated servo motor is a brand new low voltage servo product independently developed by NiMotion. Based on the leading MBD development method and integrated development concept, it integrates permanent magnet synchronous motor The encoder and servo drive are integrated, using FOC field-oriented control technology and SVPWM (space vector modulation) technology, supporting EtherCAT / CANopen bus servo control, with volume The small and simple wiring features are widely used in AGV, mobile robots, collaborative robots and other scenarios.
PMM40 features
·Highly integrated design reduces installation complexity and saves space ·Eliminate the matching process between the driver and the motor, reduce the cost of use ·Adopt EtherCAT / CANopen protocol (DS402) ·Wide voltage input (16 ~ 52VDC), can use battery power supply ·Optional power-off brake protection ·Integrated single-turn absolute value encoder, zero point memory within limited range ·Provide speed and position feedforward parameter configuration to improve response speed ·Integrated I / O, can be set to positive limit, negative limit, origin, multi-function digital output, pulse input detection ·Real-time fault monitoring and protection functions, including over-current, I2T overload, over-voltage, under-voltage, over-heat, over-speed, over-tolerance protection ·Provide application solutions and development kit support for multiple scenarios to shorten the user's development cycle ·Customizable features in multiple sports modes: dual-wheel differential drive mode, wheelset slip alarm, etc.
