Omron R7M-A10030-BS1 SmartStep AC Servo Motor with Brake
Product Overview
The Omron R7M-A10030-BS1 is a 100W AC servo motor from the SmartStep A family, designed for simple, cost-effective positioning applications. It includes an integrated 24 VDC holding brake, making it specifically suitable for vertical axes (Z-axes) where load holding is required when power is removed. This motor is well-suited for semiconductor manufacturing equipment, small robots, and precise indexing tables.
Key Specifications
Model: R7M-A10030-BS1
Series: SMARTSTEP A
Rated Output: 100 W
Voltage Rating: 230 VAC
Rated Speed: 3,000 rpm
Rated Torque: 25.49 oz-in / 180 mN·m
Maximum Torque: 135.95 oz-in / 960 mN·m

Design and Construction
The square 40 mm frame size (1.575 inches) and 8.60 mm shaft diameter allow it to fit into compact machinery designs. The 3000 rpm nominal speed is ideal for high-speed indexing and light-duty material handling, while the 960 mN·m peak torque provides ample force for intermittent loads.
Industrial Applications
Applications include vertical axis lifts, gantry pick-and-place machines (Z-axis), conveyors with stopping precision, and printing/labeling equipment.
PLC Integration and Compatibility
The R7M-A10030-BS1 integrates seamlessly with Omron’s SmartStep A servo drives, using simple pulse-train (step/direction) control from a PLC’s high-speed output. When using the motor brake, it is recommended to use a separate 24V supply for the brake to avoid voltage drops during motor operation.
Conclusion
The Omron SmartStep A R7M-A10030-BS1 combines affordability with essential servo performance, offering reliable motion control for simple automation tasks where position retention is critical.
