Stepper Motor System with Medium Torque Drive
Description
This bipolar stepper motor system implements an MSP430: a DRV8818: and a NEMA 23 motor. It's suitable for applications requiring up to 140 oz-in of torque: and up to 800 RPM. Motor voltage support is 8V to 35V: and max current is 2.5A. A multitude of configuration options allow fine tuning of the current waveform: including the regulated current level: the microstepping applied: H-bridge FET states during current decay: the time interval of current decay: and current deglitch time. The motor drive stage has integrated protection from short-circuit: shoot-through: under-voltage: and over-temperature.
Features
- Highly configurable current waveform allows maximum tunabilityIntegrated power FETs support 8V to 35V and 2.5AMotor speed is easily controlled by the STEP frequencyHardware state machine modulates current with up to 1/8 microstepping for a smooth motion profileIntegrated protection for short-circuit: shoot-through: under-voltage: and over-temperature Note:Motor must be ordered through the manufacturer
Applications
- Pachinko machine
- Laser distance meter
