New panel-mount servo drives from AMC for brushed, brushless dc motors
The AB25A100 PWM servo drive from Advanced Motion Controls is designed to drive brushless and brushed dc motors at a high switching frequency. The drive is fully protected against over-voltage, under-voltage, over-current, over-heating and short-circuits across motor, ground and power leads. Furthermore, the drive can interface with digital controllers or be used stand-alone, and requires […]
Single-chip brushless dc (BLDC) driver extends runtime off batteries
STSPIN233 low-voltage motor drivers from STMicroelectronics excel in single-shunt and three-shunt brushless-motor driving. They include a 200mΩ 1.3Arms power stage, in a slim and compact 3mm x 3mm package. The STSPIN233 also has the industry’s lowest standby current, at less than 80nA. What’s more, it can be put into standby mode under logic control, making […]
What’s the difference between ac and dc stepper drives?
Drives for stepper motors can have inputs that are either ac or dc. What happens inside the drive is that the input signal is converted to a series of square wave pulses that are applied to the motor’s windings to power the motor and produce motion. However, stepper motors themselves function as ac motors (they […]
