Product Description:
The SF-A2.0020.060-00.015 servo motor is produced by Bosch Rexroth Indramat within the SF Servo Motors series. As a brushless servomotor with permanent-magnet excitation, it converts drive current from a matched inverter into precise rotary motion for positioning axes, pick-and-place modules, or high-speed spindles in automated machinery. Heat generated during operation is removed through natural convection, so no external blower is required. The motor integrates with compatible drive controllers through a single power connector and a separate feedback cable. This arrangement supports orderly cable routing and helps keep feedback signals separate from motor power conductors.
Its electrical backbone is a 670 V DC link that delivers the field-oriented current required by the sinusoidal back-EMF windings. The motor reaches a rated speed of 6000 rpm, enabling direct coupling to fast-moving shafts without intermediate gearing. With a 0.74 Nm/A torque constant, the controller can estimate output torque from measured phase current, which helps support stable control behavior. Dynamic response is improved by the low 3 × 10⁻⁴ kg·m² rotor inertia, permitting rapid acceleration and stopping cycles. The IP67 enclosure helps protect internal components from dust and washdown exposure. The square 100 mm flange size matches common IEC mounting patterns for straightforward mechanical installation.
When motion starts from standstill, the drive must overcome a 2.0 Nm locked-rotor torque and supply a 2.7 A locked-rotor current, which affects fuse sizing and short-term thermal loading. The absolute encoder furnishes 8 million increments per revolution of position feedback, giving very fine resolution for contouring tasks and precise speed regulation. A pair of integrated NTC temperature sensors report winding heat buildup so the controller can reduce output or shut the motor down before insulation is overstressed. High feedback resolution also supports smooth low-speed interpolation and accurate position tracking during complex motion profiles.
