Product Description

The DFSM-0145B-202A is an AC servo motor and has a high efficiency, good torque to inertia ratio and offers precise motion control in industrial automation applications. Designed and manufactured by Sanyo Denki it is in accordance with the DFSM AC Servo Motors series.

The DFSM-0145B-202A Servo Motor torque generating capability is 3.6 kgcm which means it can exert 3.6 kilogram-centimeters of force at its rated operating conditions and also determines the load the motor can drive. It dissipates heat to avoid overheating with forced air cooling which means air is directed over the motor using an internal/external fan. The electric power which this module consumes during operation is 1000 Watts which suggests it is a low-power servo motor, suitable for precise and small automation tasks. It comes with a rotation speed of 3000 revolutions per minute which is a standard speed for many servo motors that balances high-speed and accurate positioning. It is featured with an absolute encoder which remembers position even when powered off, crucial for applications requiring continuity. The weight of this module is 0.76 kg which determines how heavy the motor is and affects portability, mounting and mechanical design considerations.

The DFSM-0145B-202A servo motor is capable of handling short bursts of extra torque (1.5x to 2x rated torque) before overheating which is useful for applications with sudden load changes. Its encoder has resolution of 4096 pulses/ revolution typically which means it can detect 4096 discrete positions per revolution and enables greater accuracy in movement. It is a low inertia motor which means it can accelerate and decelerate quickly and is suitable for fast and precise movements, common in robotics, CNC machines and pick and place systems.

Frequently Asked Questions about DFSM-0145B-202A

Q: How does the absolute encoder in DFSM-0145B-202A improve position tracking accuracy?

A: The absolute encoder ensures precise position tracking by retaining position data even when powered off. This eliminates the need for homing at startup, improving efficiency.

Q: Why is forced air cooling used in the DFSM-0145B-202A instead of passive cooling?

A: Forced air cooling actively dissipates heat, preventing thermal buildup and ensuring stable operation. This allows the motor to maintain consistent performance even under extended or high-load conditions.

Q: How does the low rotor inertia in DFSM-0145B-202A enhance dynamic performance?

A: Low inertia enables rapid acceleration and deceleration, improving responsiveness in applications requiring quick motion changes. This makes it ideal for robotics, CNC machines, and high-speed automation.

Q: How does the 3000 RPM speed of DFSM-0145B-202A benefit automation applications?

A: The high speed allows for faster task execution while maintaining accuracy. It ensures smooth and efficient motion control in industrial automation systems.

Q: What impact does the 3.6 kgcm torque of DFSM-0145B-202A have on its performance?

A: This torque rating enables the motor to handle moderate loads with stability. It ensures consistent force output for precise and controlled movement in industrial applications.
