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. Feedback devices include a Resolver for the BLS Series and Hall Effect devices for the BLT Series.

Key Features:

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

Technical Specifications:

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 are specified for both BLS and BLT models.
All characteristics are measured at 25°C ambient temperature.

Brake Specifications: The BL Series offers an optional fail-safe holding brake, not available for short-length versions. Brake torque and inertia are specified for different sizes.

Performance Curves: Torque versus speed performance curves are provided for various models, illustrating the motor's operational capabilities.

Resolver and Encoder Specifications:

Resolver specifications include input voltage/frequency, primary element, number of speeds, transformation ratio, electrical error, dielectric strength, mass, rotor moment of inertia, and operating temperature range.
Encoder specifications detail waveform type, line counts, channels, supply voltage, frequency response, and operating temperature for different encoder types (A, H, K).

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

The BL Series are synchronous electrical servomotors, with 3 winding phases, supplied with Sinusoidal or Trapezoidal current wave forms. The Feed-Back devices that produce the synchronization signal and speed (position, also in the Sinusoidal case), are a Resolver (BLS Series) or a Hall Effect devices (BLT Series). This "BRUSHLESS" technology provides: • High dynamic response. • Full speed condition, not limited by the "Brush Sparking effect". • High thermal and dynamic characteristics, because of the motor's windings which are located in the stators.
