Product Description:
The T840-012E59 Servo Motor provides a good balance of speed, torque, and power which makes it versatile for a range of motion control applications. It is part of the T SANMOTION Servo Motors series and is built by Sanyo Denki .
The T840-012E59 servo motor standard operating speed is 2500 min-1 when running at its rated conditions. Its shaft includes a keyway, which helps in securely mounting couplings, pulleys, or gears which prevents slippage. The weight of this model is 3.4 kg and it is able to operate at a maximum speed of 4000 min-1. It is IP43 rated which means it is protected against solid objects and also against spraying water at angles up to 60 from vertical. It does not include a built-in tachometer which is used for speed feedback. It comes with a 1-meter (1000 mm) lead wire, which defines the pre-installed wiring length for electrical connection. This model armature operates at 85V which means this voltage is needed to power it under normal conditions. It is not designed for harsh environments with oil, moisture, or contaminants because it does not have an oil seal. It has a lead wire connection rather than a connector plug that requires direct wire attachment.
The T840-012E59 servo motor can continuously hold 1.70 Nm without overheating when stalled, which is critical in applications where the motor may need to hold position for extended periods. In stalled conditions, this motor delivers a maximum torque of 12 Nm. This motor is designed to operate within a temperature range of 0 to 40C. Operating outside of this range will require additional temperature solutions.
Frequently Asked Questions about T840-012E59:
Q: How does the lead wire connection benefit the T840-012E59 Servo Motor installation process?
A: The lead wire connection allows for a direct and secure electrical setup, ensuring stable performance. It eliminates the need for additional connectors, reducing setup complexity.
Q: Why does the T840-012E59 Servo Motor have a keyed output shaft, and how does it help?
A: The keyed shaft prevents slippage when transmitting torque to couplings, pulleys, or gears. This design ensures precise positioning and enhanced mechanical stability in motion control applications.
Q: What is the advantage of the T840-012E59 Servo Motor’s 87.5 mm flange size in industrial applications?
A: The φ87.5 mm flange provides a standardized mounting interface for compatibility with various mechanical assemblies. It simplifies integration into existing industrial automation setups.
Q: How does the peak stall torque of 12 Nm enhance the T840-012E59 Servo Motor’s performance?
A: The 12 Nm peak stall torque enables the motor to handle high startup loads without performance drops. This feature is essential for applications requiring sudden torque surges.
Q: Why is an IP43 protection rating used for the T840-012E59 Servo Motor instead of higher ratings?
A: The IP43 rating balances cost and protection, making it suitable for clean indoor environments. It provides sufficient resistance to dust and water spray while maintaining efficiency.
