EAO Ltd announces the UK availability of Sanyo Denki’s new 56mm stepper motor with integrated driver, a compact motion solution designed to reduce wiring, save installation space, and deliver precise control for automation, robotics, and conveyor applications.
Building on Sanyo Denki’s reputation for precision engineering, this integrated motor-and-driver unit combines high performance with a compact footprint, helping to simplify system design while improving overall reliability.
Space-Saving, Reduced Wiring
By integrating the motor and driver into a single unit, wiring requirements are significantly reduced. The motor can be operated using as few as five wires for power and communication, with direct connections for limit sensors and homing signals further simplifying equipment design.
Precise and Reliable Motion Control
The high-performance stepper motor ensures accurate, repeatable positioning regardless of load. This makes it well suited for applications requiring precision, including conveyor systems, automated machinery, and packaging equipment.
Simple Setup and Operation
The integrated driver supports standard motion commands, including:
- Positioning
- Continuous rotation
- Homing
Key parameters such as position, speed, and acceleration can be configured quickly, enabling fast commissioning and easy optimisation.
Smooth Motion with S-Curve Acceleration
To reduce mechanical stress and improve motion smoothness, the motor offers two S-curve acceleration/deceleration profiles:
- Type 1: Peak acceleration between 25–75% of the cycle, achieving up to 1.25× linear acceleration
- Type 2: Peak acceleration at 50% midpoint, delivering up to 1.9× linear acceleration
These profiles help minimise vibration and improve performance during speed transitions.
Technical Highlights
Two versions are available:
- DB31F561S-50 – 0.14 Nm holding torque, 56 × 76 mm
- DB31F562S-50 – 0.24 Nm holding torque, 56 × 88 mm
Key specifications:
- 24 VDC ±10%, 2 A
- RS-485 communication (38400 bps, up to 16 axes)
- Open-loop control, 1/8 micro-step
- Operating temperature: 0–50°C
I/O:
- 5 photocoupler inputs (limits, homing, rotation direction, emergency stop)
- 2 photocoupler outputs (operation, alarm signals)
The motors are designed for industrial environments, with vibration resistance from 10–2000 Hz and built-in protection for voltage fluctuations, fuse faults, and CPU errors.
