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.

Among the many features that can be integrated are: Pulse/direction driver, serial RS485 position controller with graphical programming, point-to-point or multiaxis operation up to 255 axes on the same RS485 bus, CANOpen DS-301 and DSP-402, optional absolute singleturn magnetic encoder with resolution of up to 1,024 pulses/revolution for stall detection, 8 I/O that can be configured as input, output or 10bit analogue input, electronic gearing for following an encoder or pulse train in an arbitrarily selectable controlled ratio, and high speed position capture.

The MIS23 Series of stepper motors follows the same protocol as MAC motors so that MAC motors and QuickStep motors can be connected to the same RS485 bus, and a double voltage-supply is available so that position and parameters are maintained during emergency stop. They also feature: Fixed 1,600 pulses/revolution for versions with built-in position controller, 200, 400, 800, 1,000, or 1,600 pulses/revolution for versions with pulse/direction inputs. All modules are supplied with M12 connectors.
