Product Description:

The MSM0303C-0300-NN-M0-CG0 is a high-performance synchronous servomotor from Bosch Rexroth Indramat, the industry leader in industrial automation. This MSM Brushless Servo Motor is for industrial applications. Compact design with 60mm frame size, space efficient without performance compromise. The motor uses natural convection cooling, a passive cooling method that cools through air movement, making installation and maintenance easy. The 3-phase motor operates on three current phases, smooth and efficient power delivery. Input voltage 230 V, 2 HP (horsepower), power output capacity.

A key performance parameter is continuous torque at a standstill, which is 1.30 Nm. This is the torque the motor can produce when stationary, which is important for holding torque or precise positioning applications. continuous current at standstill is 2.60 A. This is the current drawn by the motor to produce this standstill torque. Maximum current is 4.90 A, the current the motor can withstand for a short period, and maximum torque is 3.80 Nm, the peak torque it can generate. These values are important to understand the motor’s dynamic and load handling. Torque constant at 20°C is 0.41 Nm/A, current per torque. Voltage constant at 20°C is 15.4 V/min⁻¹, speed vs voltage. Winding resistance at 20°C is 1.10 Ohm, resistance to current flow in the windings. Winding inductance is 3.200 mH, which affects the motor’s transient response and efficiency. These electrical parameters are important for motor control and drive selection.

The motor has an optical encoder for position feedback. This encoder gives high-resolution data on the motor’s angular position for precise control and positioning in automation systems. The encoder is necessary for precise movements and repeatability of operation, which is important in high-accuracy applications. The discharge capacity of the component is 1.4 nF. This is important for the motor’s electrical behavior and interaction with the drive system. A number of pole pairs affect the motor’s speed and torque. The MSM0303C-0300-NN-M0-CG0 is compatible with frequency inverter drive systems for variable speed control and optimized performance in different applications. This is important for integration in modern automation systems.
