Product Description:

The MSK070C-0300-NN-S3-UG1-NNNN is an IndraDyn S motor designed for precision motion tasks. It features Bosch Rexroth’s advanced control technology that provides tightly regulated dynamic response across a broad speed range. This motor uses a permanently excited synchronous design with a stator winding optimized for efficient heat dissipation. This enables stable performance in continuous operation, with efficient heat management even under high load conditions. The motor’s rigid mechanical structure and thermally optimized housing allow for consistent performance in high-performance motion applications.

The MSK070C-0300-NN-S3-UG1-NNNN offers a peak speed of 5500 min⁻¹, enabling the motor to achieve high rotational velocities. With this speed capacity, the motor can handle short bursts of intense mechanical demand, enabling rapid acceleration and deceleration as needed. The motor is also optimized for peak performance with a maximum torque capability of 33.0 Nm. This capability is essential in applications that involve rapid changes in load or where brief torque spikes are common. The high peak torque provides a greater safety margin in system design, enabling reliable operation even under unpredictable load conditions. The motor is rated for a continuous current of 12.3 A at standstill, ensuring stability during prolonged idle states or precise holding tasks.

The MSK070C-0300-NN-S3-UG1-NNNN features a winding inductivity of 8.300 mH, which helps to smooth current flow and reduces ripple. This value also provides inherent filtering against high-frequency switching noise from the drive, improving the overall electromagnetic compatibility of the system. The motor is well insulated and boasts a thermal time constant of 22.0 minutes. This provides greater thermal stability during continuous or cyclical operation, allowing for better heat management during extended operating periods. The electrical insulation of the motor can withstand a maximum permissible temperature of 155°C.
