AC Servo motors MA Series

Product catalog summary

Overview: The document provides detailed specifications and performance characteristics of the MA Series AC Servo Motors, highlighting their suitability for control operations due to their short mechanical and electrical time constants, high peak torque, and fast response time. The motors are designed with a high power-to-weight ratio, making them ideal for manipulator-mounted applications.

Key Specifications:

Mechanical and Electrical Characteristics: The motors feature a high stall torque, low thermal resistance, and a high theoretical acceleration. They are designed with an air gap, small diameter, and short length.
Performance Curves: The document includes performance curves for different models (MA-3, MA-6, MA-10, MA-20, MA-30, MA-45, MA-55), showing torque versus speed at 25°C ambient temperature.
Technical Specifications: Detailed specifications include maximum mechanical speed, stall torque, stall current, peak torque, torque-weight ratio, EMF constant, torque constant, reluctance torque, winding resistance, winding inductance, rotor inertia, mechanical time constant, electrical time constant, thermal time constant, thermal resistance, mass, radial load, axial load, insulation, and protection class.
Brake and Resolver Specifications: The MA Series motors incorporate a fail-safe holding brake and resolver specifications, including input voltage/frequency, transformation ratio, electrical error, dielectric strength, mass, rotor moment of inertia, and operating temperature range.
Dimensions and Accessories: The document provides detailed dimensions for each motor model and lists optional accessories such as encoder kits.

Critical Information: The motors are designed to operate efficiently without a separate position sensor, using a resolver for position feedback and speed/current information. The motors are protected with Class-F insulation and IP-54 protection, ensuring durability and reliability in various applications.
