Product Description:
The MDD115A-N-020-N2L-130PB0 AC Servo Motor is engineered for demanding automation systems requiring consistent torque and reliability. The motor offers durable design, operational accuracy, and compatibility with Bosch Rexroth Indramat drive systems.
The MDD115A-N-020-N2L-130PB0 AC servo motor operates at a nominal speed of 2000 RPM. It delivers a continuous standstill torque of 28.0 Nm with a continuous current draw of 27.8 A under thermal conditions defined by the Bosch Rexroth Indramat. The motor uses three phase AC power and is equipped with a digital servo feedback system with an integrated multiturn encoder for precise position control. The AC servo motor is capable of delivering a theoretical maximum torque of 87.1 Nm that is achieved at a peak phase current of 125.2 A. The rotor's moment of inertia is 1.23 × 10⁻² kg·m² that enables rapid acceleration and deceleration suitable for high dynamic response requirements. This torque and inertia profile supports applications with fast load transients, precise motion control and high bandwidth servo systems. Its structural design offers effective heat dissipation which enhances thermal efficiency and motor life. The motor ensures high contouring accuracy at elevated feedrates particularly during high speed cutting operations. This is achieved through precise torque control, rapid acceleration/deceleration capabilities and minimal position lag. This also enables consistent toolpath tracking even under dynamic load conditions.
The MDD115A-N-020-N2L-130PB0 AC servo motor has a torque constant of 1.01 Nm/A at 20 °C for precise torque generation per unit of current. The phase to phase winding resistance is 0.30 Ω which directly impacts copper losses (I²R losses) and voltage requirements during operation. The MDD series AC servo motor is engineered to perform consistently in high load high frequency operations.
