Introduction of new stepper motors from company
Festo introduces the EMMT-ST, the company’s new stepper motor series. Festo incorporated "the most in-demand stepper motor features and options for this new product, including absolute encoders, IP65 protection, holding brakes, and control via a single cable," the company said in a September 19 press release emailed to Electrical Apparataus.
OEMs have the choice of an absolute single-turn encoder or absolute multi-turn encoder, which are both battery-free. Absolute encoders save time when the machine starts up – no need to re-home the motor. And IP65 protection means the motors can be used in harsher environments than typical motors.
The optional holding brake saves OEMs from having to integrate these components to effectively clamp the motor for vertical applications. And the EMMT-ST features a single cable connector for the motor power and encoder signals. This swivel connector allows the motor’s single cable to be pointed at any angle within 310° of the motor’s orientation.
OEMs can enter application parameters into the Festo Electric Motion Sizing design and simulation tool to find the right combination of servo drive, motor, and actuator for the budget and application. Once the servo-motion solution is approved, the correct size components with accessories can be ordered as a complete bill of materials created directly in the software. CAD files are immediately available so engineering work can continue while Festo gathers the parts, which are shipped as a group to streamline installation.
