PMD Juno Velocity and Torque Control IC Family
PMD Juno Velocity and Torque Control IC Family
Performance Motion Devices Juno is a family of motor-control integrated circuits with distinct velocity, torque and step-motor members. This review focuses on choosing the correct control function, motor support and package for a custom controller board.
Review Summary
Juno is useful for OEMs designing their own motor-control electronics with a clearly defined loop and motor requirement. Select the complete IC reference and external power stage; a Juno control chip is not a finished amplified drive, and family interface lists do not apply uniformly to every member. The same MC71113, MC73113 and MC78113 devices also support an outer-loop application: an external process sensor supplies pressure, temperature or another measured quantity through the specified analog or digital SPI path. PMD describes a PID outer loop that commands the downstream PI velocity loop. This is an additional control use of the identified IC family, not a separate motor amplifier or a different chip with an interchangeable model number.
Velocity examples MC71113 for DC brush, MC73113 for brushless DC, MC78113 for selectable DC brush/brushless DC in current velocity product information Torque examples MC71112/MC71112N for DC brush; MC73112/MC73112N for brushless DC Power-stage scope External bridge-type switching amplifier and supporting circuitry required Package selection Velocity examples use 64-pin TQFP; specified torque N variants use 56-pin VQFN Interfaces Serial, SPI, analog commands and CAN availability depend on the exact subfamily and function Development tools Matched developer kit, Pro-Motion and C-Motion host SDK as applicable Velocity IC loop rates MC7X113: programmable velocity loop up to 10 kHz; current loop 20 kHz Velocity IC PWM settings MC7X113: 20, 40, 80 or 120 kHz Velocity IC quadrature input MC7X113: maximum 40 Mcounts/s; not an axis accuracy rating Applications and Industries
OEM motor-control boards for medical and laboratory equipment, robotics and spindle control; suitability depends on the exact Juno IC, external amplifier, feedback and final system validation.
