SBB14 – Signal Breakout Box

Magtrol SBB 14 Signal Breakout Box

Product Description

Magtrol’s SBB14 Signal Breakout Box is designed to assist in the monitoring of speed, torque and index signals obtained from either a Magtrol dynamometer or torque transducer. The easy-to-use SBB14 is simply inserted in series between a Magtrol controller and any Magtrol dynamometer or torque transducer. Connections are made via 14-pin signal cables.

Speed, torque and index signals are then outputted through BNC connectors to an oscilloscope or other DAQ instrumentation device. A toggle switch is now provided to allow switching between a torque transducer and an external encoder wired to the encoder input. The SBB14 Signal Breakout Box is a convenient and reliable accessory that reduces the necessary wiring required for signal monitoring.

Features

  • Two 14-Pin Connectors: provides an in-line connection between a Magtrol DSP Controller and
    a Dynamometer or a Torque Transducer
  • Four BNC Connectors: provides easy access to Tach A, Tach B, torque and index signals
    for connecting to an oscilloscope or other data acquisition (DAQ) device
  • Sturdy Assembly: packaged in a shielded aluminum case with metal mounting flanges
    An encoder input is provided for connecting high resolution encoders
  • An internal jumper is provided for suppling a regulated 24 VDC supply to a transducer
  • A toggle switch has been added to provide switching between torque transducer and an
    external encoder

                    [post_content] => Eddy-Current Brake Dynamometers (WB Series) are ideal for applications requiring high speeds and also when operating in the middle to high power range. Eddy-Current Brakes provide increasing torque as the speed increases, reaching peak torque at rated speed. The dynamometers have low inertia as a result of small rotor diameter. Brake cooling is provided by a water circulation system, which passes inside the stator to dissipate heat generated by the braking power, providing high continuous power ratings (max. 140 kW). The WB dynamometers have accuracy ratings of ± 0.3% to 0.5% full scale (± 2% for WB 2.7), depending on size and system configuration. Additional options include: high-speed version, speed pickup, mechanical rotor blocking device, OEM version IS and vertical mounting.

Features

  • 13 Models with Maximum Torque from 300 mN·m to 560 N·m (42 oz·in to 413 lb·ft)
  • Braking Power: from 500 W to 140 kW
  • Stable Braking Torque, without Shock
  • Low Moment of Inertia
  • Low Residual Torque
  • Operating Direction CW / CCW
  • Braking Torque Measurement Integrated
  • High Rotational Speed
  • Integrated Optical Speed Sensor
  • Special designs available upon request

Operating Principles

The WB Eddy-Current Dynamometers develop their full power at high rotation speeds. The WB Series is particularly intended for motors which rotate at high speeds, up to 65 000 rpm (up to 100 000 rpm with WB 23 / 27; see specific datasheet). The braking torque depends on the rotation speed. Optical Speed Sensor Each WB Series Dynamometer has an optical speed sensor delivered as standard. WB 2.7 & WB 43 has an optical speed sensor with a 30-PPR encoder; WB 65, WB 115 & WB 15 has an optical speed sensor with a 60-PPR encoder.

To better integrate dynamometers into systems, Magtrol offers both long and short base plates.  The shorter base plate facilitates easier motor mounting when used with T-slot tables and Magtrol Adjustable Motor Fixtures, where as the long base plates are better suited for table top testing.

Features

  • 16 Standard Models with Maximum Torque from 2.5 oz·in to 500 lb·in (18 mN·m to 56.5 N·m)
  • Hysteresis Braking System: Provides precise torque loading independent of shaft speed
  • Motor Testing from No Load to Locked Rotor
  • Accuracy: ±0.25% (Full Scale)
  • Air Flow Sensor: For protection against overheating and operator error
  • Standard Torque Units: English, Metric and SI
  • Base Plate: Available in long or short versions
  • Custom Dynamometers: for special torque and speed requirements
  • Easy Calibration

The Hysteresis Braking System

All Magtrol Hysteresis Dynamometers absorb power with a unique Hysteresis Braking System which provides frictionless torque loading independent of shaft speed. The Hysteresis Brake provides torque by the use of two basic components - a reticulated pole structure and a specialty steel rotor/shaft assembly - fitted together but not in physical contact. Until the pole structure is energized, the drag cup can spin freely on its shaft bearings. When a magnetizing force from the field coil is applied to the pole structure, the air gap becomes a flux field and the rotor is magnetically restrained, providing a braking action between the pole structure and rotor.
