MDD093B-N-030-N5L-110PB0

Product Description:

Bosch Rexroth Indramat manufactured the MDD093B-N-030-N5L-110PB0. The Bosch Rexroth Indramat MDD093B-N-030-N5L-110PB0 synchronous motor has a nominal speed of 3000 min⁻¹, which is the speed under rated load. For applications that require synchronized motion or constant velocity across complex assemblies, this speed is key to determining the mechanical output of the system it drives. To evaluate dynamic characteristics like velocity control and load response, the nominal speed is related to the motor’s frequency and pole count; in applications where material transport, robotic articulation or processing equipment, where deviation can add up to errors or system instability, precise speed control is critical. This value is important for drive selection and tuning as motor control methods must keep the balance between rotor speed, torque generation and temperature limits. This motor shows the importance of temperature management in performance with a standstill torque of 24.0 Nm, which increases to 35.0 Nm when actively cooled.

In static or slow-moving applications, more cooling capacity allows for higher current injection without thermal degradation and therefore higher torque production. Reducing wear, improving repeatability and shielding downstream components from mechanical stress all depend on the ability to statically withstand high torque within temperature limits. Since current and magnetic flux in the stator windings are directly related, the continuous current rating at a standstill is 41.4 A, which increases to 60.3 A with forced cooling. This rating is important for torque production. As long as thermal equilibrium is maintained and the magnetic core doesn’t saturate, torque increases with current. The motor can produce more torque without thermal overload thanks to active cooling mechanisms that allow for higher current draw. This is important for applications that require sustained force application at low or zero speed. Also, the motor’s short-term reaction capability – which is important during fast acceleration or transient load events – is shown by its peak current capacity of 186.0 A.

Angular acceleration and deceleration are influenced by the rotor’s moment of inertia which is 58×10⁻⁴ kg·m². In servo-controlled systems, lower values mean faster dynamic response. A key component for precise torque control via current management, the torque constant is the torque per ampere and is 0.58 Nm/A at 20°C. The motor’s reaction to sudden voltage changes during control events is influenced by the winding resistance of 0.18 Ω and inductance of 2.1 mH, which defines both steady-state voltage drop and dynamic current response. Duty cycle estimates are directly influenced by the thermal time constant, which is the time it takes for the motor to heat up under load (50 minutes without cooling, 45 minutes with cooling). This motor operates reliably between 0°C and +45°C, is IP65 protected, and is Class F insulated. It’s made for harsh industrial environments exposed to dust, water and high temperatures.
