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 mechanical and electrical properties.

Key Features:

Short mechanical and electrical time constants for fast response and high peak torque.
High theoretical acceleration and stall torque, with low thermal resistance for cooler operation.
High power-to-weight ratio, making them ideal for manipulator-mounted applications.
Air gap design with small diameter and short length.
Integrated resolver for position feedback, eliminating the need for separate sensors in many applications.

Performance Curves: The document includes performance curves for various models (MA-3, MA-6, MA-10, MA-20, MA-30, MA-45, MA-55), showing torque versus speed characteristics.

Technical Specifications:

Maximum mechanical speed: 6000 rpm for most models.
Stall torque and current, peak torque, torque-weight ratio, EMF constant, and other electrical parameters are specified with tolerances.
Thermal and mechanical time constants, thermal resistance, and mass are provided.
Protection class: IP-54, with Class-F insulation.

Brake and Resolver Specifications:

Fail-safe holding brake options are available for different models, with specifications for mass, torque, and inertia.
Resolver specifications include input voltage/frequency, transformation ratio, electrical error, and operating temperature range.

Dimensions and Accessories: Detailed dimensions for each motor model are provided, along with optional accessories such as encoder kits and mounting specifications.

• The short mechanical time constant makes it ideal for control operations. • An extremely short electrical constant provides high peak torque at high speed. • A high "theoretical" acceleration gives an extremely fast response time. • High stall torque due to the absence of commutators bars. • Low thermal resistance provides low working temperatures. • High power to weight ratio, ideal for manipulator mounted motors. • Air gap design, small diameter and short length. • For many applications a separate position sensor is not required, the resolver can be used for deriving a position feed back...
