Product Description:
The brushless motor SF-A5.0700.020-00.065 is designed by Bosch Indramat with a smooth cylindrical shaft that is 80 mm long. It is installed using standard flange to facilitates proper speed and positioning. This motor comes under the SF series and has an STG absolute encoder, which provides 800000 counts per revolution and ~20 arcseconds accuracy.
The SF-A5.0700.020-00.065 motor features 69 Nm of torque and its continuous spinning speed is at 2000 rev/minute. The inertia of the rotor is 0.00257 kgxm^2 and its turning effect constant is 2 Nm/A. It utilizes up to 34 A of locked-rotor current under load conditions. The SF-A5.0700 motor has a plug-in power connector for power lines connectivity and it take shielded cable of 10 square millimeters for motor and 1.5 mm square for the encoder wiring. The SF-A5.0700 motor uses self-cooling through natural convection/radiation, though it does not have a fan unit but an optional blower can be installed as a surface ventilation system, depending on the site conditions. Its insulation belongs to F in order to guarantee the thermal safety and continuous duty operations on hot industrial sites. The SF-A5.0700 motor comes IP67 protected to safeguard inside components from outer pollutants that derates the performance and its body temperature range is 23 degrees F to 311 degrees F, which is monitored by thermistors.
The SF-A5.0700.020-00.065 motor output shaft lacks protection and its ball bearings are located on the flange side. It does not include a brake unit, though external arrangement of 24 V DC holding brake is supported. The mass of the motor without a brake system is 50 kg and it can tolerate up to 6 g of shock resistance. The SF-A5.0700 motor is used in applications that require accurate position, speed and torque control.
Frequently Asked Questions about SF-A5.0700.020-00.065:
Q: How does the 800,000-count STG encoder in the SF-A5.0700.020-00.065 improve performance?
A: The high-resolution STG encoder enhances positional accuracy and speed feedback, which is critical for synchronized multi-axis systems and fine motion control.
Q: Why is a plug-in power connector used in the SF-A5.0700.020-00.065 motor?
A: It simplifies installation and ensures a secure, vibration-resistant electrical connection, especially useful in dynamic industrial environments.
Q: What is the role of the thermistors in the SF-A5.0700.020-00.065 motor?
A: Thermistors continuously monitor internal temperature, enabling thermal protection and preventing overheating during long duty cycles or high-load operations.
Q: How does the 2 Nm/A torque constant benefit the motor's application?
A: This high torque constant allows precise control at lower currents, increasing efficiency and enabling better control in servo-based applications.
Q: Why is insulation class F important in the SF-A5.0700.020-00.065 motor?
A: It allows operation at higher internal temperatures (up to 155 degrees C), supporting reliable performance in thermally demanding industrial environments.
