HSI's bipolar chopper drive has been designed for easy setup and use - just connect a single power supply and a motor and it's ready to run.
A chopper drive is a power-efficient method of current driving a stepping motor to obtain higher stepping rates.
Torque, likewise, is maintained which otherwise would have diminished due to the effects of counter EMF and increased coil impedance.
HSI's bipolar chopper drive (40105), available from Servotechnic, has been designed for easy setup and use - just connect a single power supply and a motor and it's ready to run.
This makes the 40105 drive ideal for those rapid prototype projects where ease of use and quick delivery are important.
40105 chopper drives are available for immediate delivery from stock.
Motor current is set using an onboard potentiometer.
No external current setting resistors are required.
This feature-packed drive provides all basic motor controls, including full or half stepping of bipolar steppers and direction control.
An oscillator circuit is standard on the drive with an onboard speed control potentiometer.
In addition, external input/output signals allow complete remote control of all drive functions.
