Product Overview
The MOOG SM23165D is a Class 5 D-Style SmartMotor from Moog Animatics, combining a NEMA 23 servo motor with an integrated controller, amplifier, encoder, and communications functions. This integrated architecture reduces the need for separate motion-control components and is suited to compact automated equipment requiring programmable positioning and speed control. The motor provides approximately 181 W nominal continuous power, 2.05 in-lb continuous torque on the current product listing, and a no-load speed of 10,400 RPM. It also supports built-in RS-232 communication and seven channels of 5 V TTL non-isolated I/O, with optional fieldbus and 24 V I/O configurations available.

Key Features and Benefits — SM23165D
- Integrated motor, controller, amplifier, encoder, and communications bus.
- Compact NEMA 23 package for distributed motion-control applications.
- High no-load speed of up to 10,400 RPM.
- Built-in programmable motion-control capability.
- Standard RS-232 communication interface.
- Seven channels of 5 V TTL I/O included.
- Optional CANopen, DeviceNet, PROFIBUS, and expanded 24 V I/O configurations are available depending on the exact suffix and ordering configuration.
- Suitable for packaging, indexing, automation, material handling, and other servo positioning equipment.
The integrated design is the main attraction here. Personally, I would choose this type of SmartMotor where cabinet space and wiring reduction matter as much as conventional servo performance.

Installation and Maintenance — SM23165D
Before installation, verify the exact motor suffix, supply voltage, communication option, I/O configuration, shaft arrangement, and existing controller parameters. The base model can be supplied with different communication and I/O options, so the physical label should be checked against the machine BOM.
Mount the motor with correct shaft alignment and observe the specified radial and axial load limits. Confirm encoder feedback and communication before enabling motion. During commissioning, start with conservative motion parameters and verify direction, travel limits, acceleration, and stopping behavior.
Product Warranty — SM23165D
Warranty coverage depends on the supplier and purchase terms. For a maintenance spare, the receiving inspection should record the exact model, serial number, physical condition, connector condition, and functional test results.
The MOOG SM23165D is best regarded as a compact integrated servo solution for legacy and existing Class 5 motion systems, particularly where programmable motion control and reduced cabinet hardware are valuable.
