AC Servo motors BL 40 / 50 / 70 Series

Product catalog summary

Overview: The document provides technical specifications and features of the BL Series AC Servo Motors, specifically the BL 40/50/70 Series. These motors are synchronous servomotors with three winding phases and are available with sinusoidal or trapezoidal current waveforms. They utilize feedback devices such as resolvers or Hall Effect devices for synchronization and speed control.

Key Features:

High dynamic response and full speed capability without brush sparking effects.
Enhanced thermal and dynamic characteristics due to stator-located windings.
Low maintenance requirements.

Technical Specifications:

Maximum mechanical speed, stall torque, peak torque, and other parameters are provided for different voltage levels (220 VAC and 400 VAC).
Specifications include torque-weight ratio, EMF constant, torque constant, winding resistance, and inductance.
Protection class is IP-65, and insulation is Class-F.

Brake and Performance:

The BL Series offers an optional fail-safe holding brake, not available for short-length versions.
Brake specifications include torque, inertia, and mass for different sizes.
Performance curves illustrate torque versus speed for various models.

Resolver and Encoder Specifications:

Resolvers are specified by input voltage/frequency, transformation ratio, and operating temperature range.
Encoders are available in types “A”, “H”, and “K” with different line counts and frequency responses.

Dimensions:

Dimensions are provided for standard and short-length versions, with or without brake options.
