Product Description:
The SF-A2.0026.030-04.058 Servo Motor is powered by Bosch Rexroth Indramat. This device is developed for industrial automation applications. It delivers a locked-rotor torque of 2.6 Nm at full load. The locked-rotor current is measured at 1.7 A. The torque constant of this motor is 1.5 Nm per ampere. The servo motor operates at a nominal speed of 3000 rpm.
The shaft of SF-A2.0026.030-04.058 servo motor measures 14 mm in diameter and 30 mm in length. The flange size is fixed at 100 mm in width. The maximum motor length excluding the brake is 208 mm. The overall motor weight is approximately 6.2 kilograms with compact design. The compact design fits applications with limited installation space. The moment of inertia with the encoder is 4 x10-4 kgxm^2. The SF-A2.0026.030-04.058 servo motor includes a single-turn STG encoder by default. A multi-turn MTG encoder is available as an option in this motor. The encoder precision value is ~20 angular seconds per revolution. The resolution of this device reaches up to 8 million increments per revolution. The encoder system offers detailed position control for motion tasks.
The optional holding brake of the SF-A2.0026.030-04.058 servo motor has a transferable torque of 3.2 Nm. The brake torque is specified at an internal temperature of 120 degrees Celsius. The brake operates at a supply voltage of 24 volts with a ~10% tolerance. The allowed residual ripple in the voltage supply is 5 percent. The rated current required by the brake measures 0.56 amperes. The moment of inertia of the brake is calculated at 0.4 x10 kgxm^2. The mass of holding brake is limited to 0.35 kilograms. The housing of the device is built for compatibility with standard mounting interfaces.
