Description
Product Overview
The YOKOGAWA SD1100A02 / DM1000A00 is a Yokogawa DD servo actuator and motor assembly associated with the DYNASERV servo system family. The exact eBay listing identifies the combination as SD1100A02 / MOTOR DM1000A00, with Yokogawa shown as the manufacturer and the item condition listed as Used.
The SD1100A02 and DM1000A00 should be treated as a matched equipment combination rather than as a generic motor and drive. In a DYNASERV installation, the actuator/motor works with its associated servo control electronics to provide controlled rotary motion for the machine mechanism.

The public listing confirms the SD1100A02 / DM1000A00 identification, but I could not verify reliable public documentation for the exact rated torque, rated speed, feedback specification, input voltage, current, encoder resolution, shaft dimensions, or connector pinout for this particular combination. Those values should therefore be confirmed from the motor nameplate or original Yokogawa documentation rather than estimated.
Operating Principle
A direct-drive servo system places the motor’s rotary output directly into the machine’s driven mechanism, avoiding the conventional gearbox arrangement used in many servo applications.
This type of arrangement can be useful where the machine requires controlled positioning, repeatable movement, and a compact mechanical transmission path.
The actuator and motor are only one part of the complete servo system. The corresponding servo controller/amplifier, feedback system, mechanical load, and machine control software all affect actual performance.
Yokogawa DYNASERV listings also show other combinations such as an SD1200A02 controller paired with a DM1200A00 actuator, indicating that controller and actuator model matching is important within this product family.
Typical Applications
The SD1100A02 / DM1000A00 assembly can be considered for industrial equipment where a Yokogawa DYNASERV motion system is already installed.
Typical maintenance applications include:
- Replacement of a failed servo actuator
- Replacement of a damaged motor
- Restoration of legacy motion-control equipment
- Industrial machine maintenance
- Semiconductor and precision equipment maintenance
- Spare-parts inventory
- Equipment refurbishment
- Servo-system troubleshooting
Because this is an equipment-specific servo assembly, the target machine and original servo controller should be identified before ordering.
Installation & Configuration
Before installing a replacement actuator/motor, compare the original assembly with the replacement carefully.
Check:
- Complete SD1100A02 model number.
- Complete DM1000A00 motor number.
- Motor nameplate information.
- Connector type and position.
- Mechanical mounting pattern.
- Shaft or coupling dimensions.
- Feedback wiring.
- Cable routing.
- Servo controller compatibility.
Remove system power according to the machine manufacturer’s service procedure before disconnecting the motor.
Do not rotate or mechanically load the actuator during installation in a way that could damage the feedback or coupling system. After installation, verify the mechanical alignment before enabling the servo system.
Maintenance & Inspection
For a used servo actuator/motor assembly, inspect:
- Motor housing for cracks or impact damage
- Shaft and coupling area
- Mounting holes and threads
- Electrical connectors
- Cable insulation
- Nameplate and model markings
- Signs of oil, dust, or contamination
- Unusual shaft resistance or mechanical noise
- Evidence of previous repair
If the unit has been stored for an extended period, inspect the connectors and mechanical assembly before applying power.
A proper functional test should ideally be performed with the matching Yokogawa servo controller or an approved test system. Checking only winding resistance is not sufficient to establish complete servo-system functionality.
Replacement & Compatibility Notes
The safest replacement reference is the complete combination:
SD1100A02 + DM1000A00
Do not substitute a different DYNASERV model simply because it has a similar physical appearance.
For example, other Yokogawa listings show an SD1200A02 + DM1200A00 combination. This demonstrates that different controller/actuator pairings exist within the DYNASERV family, but it does not establish interchangeability with SD1100A02 / DM1000A00.
Before purchasing, compare:
- Actuator model
- Motor model
- Servo controller model
- Motor connector
- Feedback configuration
- Mechanical dimensions
- Mounting arrangement
- Machine model
- Original equipment documentation
