Product Description:
The MAC041A-0-IS-4-E/050-A-0/WI651LV Servo Motor is a compact, reliable solution designed for precision motion control as it features an incremental encoder and tachofeedback for accurate speed and position monitoring. Manufactured by Bosch with quality and versatility in mind, it suits complex servo operations.
The MAC041A-0-IS-4-E/050-A-0/WI651LV servo motor power connector is located on the side A which affects how it is mounted and wired in an application and is important for space constraints and cable routing. The type of signal generated by the encoder or feedback system is square wave signal which is a common format for incremental encoders and is used to determine position, speed and direction of the motor shaft. The thermal tolerance of the motor’s internal insulation system is determined by class F which allows for operation at up to 155°C. and affects the amount of heat it can handle safely before risking insulation failure. It is a small or mid size servo motor with a size of 41. It can dissipate heat without fans or forced cooling which means it relies on airflow around it naturally. For storing the module the safe temperature range is -20 to +80 centigrade.
The MAC AC Servo Motors series model does not include a brake to hold its shaft in place when power is off, which matters in vertical or safety-critical applications where movement needs to be prevented when idle or during power loss. It comes with an incremental encoder (rather than absolute) that is mounted in the standard way and provides relative position and speed feedback, but does not retain position when power is off. It has a tachofeedback system which means a tachogenerator gives analog speed feedback and an encoder gives position feedback.
Frequently Asked Questions about MAC041A-0-IS-4-E/050-A-0/WI651LV:
Q: Why is natural convection cooling used in the MAC041A-0-IS-4-E/050-A-0/WI651LV servo motor?
A: Natural convection allows heat dissipation without fans, reducing noise and moving parts. It’s ideal for compact, low-maintenance environments.
Q: How does Class F insulation benefit the MAC041A-0-IS-4-E/050-A-0/WI651LV motor?
A: Class F insulation ensures thermal reliability up to 155°C, increasing durability. It also extends operational life in high-temperature conditions.
Q: What role does tachofeedback play in servo control systems?
A: Tachofeedback provides real-time analog speed data. This enables more precise and responsive motor control in closed-loop systems.
Q: Why is square-wave signal preferred for feedback in servo motors?
A: Square-wave signals offer accurate, high-resolution feedback for motion control. It allows reliable tracking of speed and shaft direction.
Q: What applications benefit from the MAC041A-0-IS-4-E/050-A-0/WI651LV’s encoder feedback system?
A: Applications requiring high precision, such as CNC systems and robotics, benefit from incremental encoder’s fine speed and position control.
