Power Supply For Stepper Motor Driver

Driving voltage is main factor when choosing a power supply.

Power supply for stepper motor driver.

If the regen power climbs to a level beyond what can be stored e g during aggressive deceleration of large inertial loads lowering of gravitational loads etc the ideal power supply will shunt the excess energy into a load resistor to safely dissipate it. Just like most motors stepper motors have a rated voltage and current. When searching for the right power supply you ll want to check the stepper motor s specifications to find its voltage rating then multiply this number by ten. Confirm motor s rated current.

These numbers will tell you the maximum current you can expect when you hook the motor up to a certain voltage. You can find it at motor datasheet. In order to choose the best power supply for your stepper motor you ll need to add up the voltage of the motors. It is generally composed of a pulse width modulation pwm control ic and a mosfet.

Below are few tips for choosing power supply. Your stepper motor will perform even better by using a power supply rated twenty times higher than the stepper motor s voltage. Stepperonline stepper motor power supply uses modern power electronics technology to control the ratio of the turn on and turn off time of the switch to maintain a stable output voltage. A right power supply can make your stepper motor working at optimum performance instead a wrong power supply might cause low performance or larger waste of energy.

The core of the dc switching power supply is a dc dc converter and is roughly composed of a main circuit a control circuit a detection circuit and an auxiliary power supply.
