JVL says its new MIS23 QuickStep is a series of versatile, compact, economical integrated stepper motors. Integrated stepper motors in the MIS23 series have NEMA 23 flange dimensions of 57 mm by 57 mm and are available in three models with rated torques of: 1.1 Nm (MIS231), 1.6 Nm (MIS232), 2.5 Nm (MIS234) (1000 RPM @ 48VDC). To reduce cost and protect against electrical noise many of the control and communication functions have been integrated with the motor in a housing designed to provide IP42, IP55 or IP65 protection, and eliminating the need for running control and communication cables. Different PCB’s (modules) can be mounted within the housing to create an automation/motion control system that is easy to incorporate into new and existing applications, according to the company.
