Product Description:
The SF-A2.0026.030-04.050 servo motor is manufactured by Bosch Rexroth Indramat and belongs to the SF Servo Motors series. It is intended for precision position and speed control in automated assembly lines, pick-and-place stations, and compact handling modules. The motor houses a permanent-magnet brake that keeps the shaft fixed during power-off states, and its absolute value encoder supplies unambiguous position data to the drive controller, which is important for start-up referencing and in-cycle monitoring.
The brake generates a holding torque of 3.2 Nm while drawing only 0.56 A from a control circuit that must supply 24 VDC ±10%. Ripple on the brake winding is limited to 5 %, reducing residual vibration at standstill. Under rated operating conditions the rotor can reach 3000 rpm; this speed works with natural convection cooling, eliminating the need for forced air. A rotor inertia of 4 × 10-4 kg·m² supports fast acceleration without excessive drive current, and the IM B5 flange pattern lets the motor mate directly to gearheads or machine frames.
The power electronics connected to the motor must provide a DC link of 670 VDC, and the housing carries an IP67 rating so it withstands high-pressure wash-down and complete dust ingress. During locked-rotor tests the stator draws 1.7 A to produce 2.6 Nm, a value used when sizing over-current protection. The electromagnetic circuit delivers a torque constant of 1.5 Nm/A, allowing control engineers to translate commanded current into predictable shaft torque. Two integrated NTC sensors report winding temperature to the drive, and the permanent-magnet brake, 5 % residual ripple, natural convection cooling, and absolute encoder collectively establish a motor platform suited for precise yet low-maintenance automation.
