A driver is a must-have for any stepper motor. In a stepper motor system, a driver controls how the motor operates based on signals received from the controller. It is responsible for sending current through various phases in a stepper motor and also regulates the motor current (torque) and step resolution. With recent trends of minimizing machine footprint, finding space to install drivers could be challenging.
Standard Stepper Motor System Configuration
Oriental Motor is aware of this trend, and we have designed our standard stepper motor drivers with various mounting options to fit more machine designs.
CHALLENGE 1 Mount a Driver Vertically with Horizontal Connections
SOLUTION Use a Right Angle Driver with Mounting Plate
With this type of driver, the connectors face outward (parallel to the circuit board). Mating connectors are provided. A right angle driver with Mounting plate can also be used with a driver cover and DIN rail mounting bracket.

CHALLENGE 2 Mount a Driver Horizontally with Vertical Connections
SOLUTION Use a Driver with Mounting Plate
With this type of driver, the connector faces upward (perpendicular to the circuit board). Mating connectors are provided.

CHALLENGE 3 Mount a Driver Directly on a Metal Plate
SOLUTION Use a Driver without Mounting Plate
With this type of driver, the connectors face upward (perpendicular to the circuit board). Several design improvements, such as our high efficiency FETs, eliminate the requirement of a heat sink. Mating connectors are provided.

CHALLENGE 4 Mount a Driver Directly to a PCB
SOLUTION Use S-Type Drivers
This type of driver is great for engineers who prefer their own custom designs and can be installed right onto a printed circuit board (PCB) either by pin socket or direct solder. A vertical S-type and a horizontal S-type are available with either I/O only or SPI (Serial Peripheral Interface) bus communication.
