Product Description:

The model SR-A5.0700.030-00.060 is a Servo Motor designed for industrial automation. It offers precise motion control, robust construction and efficient heat dissipation. The motor features a resolver encoder, IP67 protection and conforms to multiple DIN/IEC standards.

The SR-A5.0700.030-00.060 servo motor delivers a locked rotor torque of 69 Nm that offers strong holding capability during static conditions. The torque constant is rated at 1.53 Nm/A. This indicates efficient torque generation per ampere of current. Its moment of inertia is 257 × 10⁻⁴ kgm² that supports smooth acceleration and deceleration in dynamic applications. The shaft dimensions are 32 mm in diameter and 58 mm in length. The total mass of the servo motor is 50 kg. It employs a resolver encoder that delivers a precision of ± 10 angular minutes and resolution of 8,192 increments per revolution. This encoder allows for high resolution feedback and accurate control. The SR series servo motor is protected according to IP67 standards under DIN 40050/40053 and EN 60 445. This makes it dust tight and resistant to water immersion that is ideal for harsh operating conditions. The shaft end follows DIN 748 specifications that ensures compatibility with standard keyway connections in drive systems.

Cooling for the SR-A5.0700.030-00.060 servo motor is achieved through radiation and natural convection which simplifies the installation by eliminating active cooling systems. The motor’s external surface can reach temperatures up to 100 °C during operation; a touch guard is recommended where required. The type of construction for the motor is IM B5 according to DIN IEC 34-7. This means it’s designed for flange mounting with a smooth cylindrical shaft. This supports flexible installation in horizontal or vertical orientations.
