Help please!
I am using scavanged Vexta high precision 400 steps per 360° motors (2 phase, 8 wire, at 3.9v, 2.8Ω, 1.4A in bipolar series configuration) driven by the Allegro A4983 chip. The chip carrier however requires a motor voltage of at least 8 volts, which is well above the specified 3.9 for the motors, even in the series configuration.
Is a resistor in series with the windings neccessary to bring down the voltage or can I rely on the current control of the A4983 to keep things within bounds? Are there any other strategies I should be considering here?
Any help will be much appreciated.
Thank you
