Product Description:
The MAC112C-0-HD-1C/130-A-01J1250/SQ5 Servo Motor of Bosch is designed for efficient motion control operations. It is part of the MAC AC Servo Motors series. The servo motor is known for offering dependable performance in industrial control applications.
MAC112C-0-HD-1C/130-A-01J1250/SQ5 servo motor internal winding configuration is of type D which is optimized for applications running at or near 1500 RPM and influences characteristics like voltage constant, torque constant and overall efficiency. It includes a tacho generator that outputs a voltage proportional to its speed and helps in closed loop speed control applications by providing real-time speed feedback to the controller for precise adjustments. Its stator windings have a phase to phase resistance of 0.090 Ω due to which it generates less heat and gives better efficiency at higher currents. It also has some non-standard feature(s) tailored for a particular customer or application. It does not feature an integrated brake to hold position when power is removed. It includes an external blower fan, mounted on the right side, powered by AC 230V which significantly improves cooling performance and allows for higher continuous current and torque handling by actively dissipating heat.
The MAC112C-0-HD-1C/130-A-01J1250/SQ5 servo motor can sustain 27 nm of torque continuously without moving and assuming proper cooling which is a critical parameter for holding and low-speed applications. The module takes 100 min to reach 63% of its maximum temperature rise under constant load. The size of the centering pilot on the motor's mounting face is 130 mm which ensures mechanical alignment during installation. The module has a 0.730 Nm/A value of torque constant which shows the amount of torque it produces per ampere of current. While producing the rated standstill torque it draws 41 amperes of current continuously under proper cooling.
Frequently Asked Questions about MAC112C-0-HD-1C/130-A-01J1250/SQ5:
Q: How does the 130 mm centering diameter help during motor installation?
A: It ensures precise mechanical alignment between the motor and mounting surface. This improves stability and reduces vibration in high-precision industrial setups.
Q: Why is a tacho generator used instead of an encoder in this servo motor?
A: The tacho generator offers reliable real-time speed feedback, making it ideal for older or analog control systems requiring analog velocity signals.
Q: How does the MAC112C-0-HD-1C/130-A-01J1250/SQ5 improve torque performance with the blower?
A: The blower actively cools the motor, allowing it to maintain higher torque continuously. This prevents thermal overload and extends motor life.
Q: What role does the resistance of 0.090 Ω play in overall performance?
A: Lower resistance minimizes power loss and heat generation. This enhances thermal efficiency and allows for higher current operation without overheating.
Q: How does the torque constant of 0.730 Nm/A benefit precise applications?
A: It allows the motor to produce more torque per amp, enhancing fine motor control. This is particularly useful in applications needing consistent force at low speeds.
