Dynamometer Tables

Dynamometer Table

Product Description

Test from a stationary position or move a dynamometer to alternate testing stations with ease with Magtrol’s Dynamometer Table. The stand is designed from lightweight aluminum with casters for smooth mobility, and is sturdy enough to support even the heaviest of Magtrol dynamometers. The design can be retrofitted to any Magtrol dynamometer and is easily reconfigured for added versatility.

Features

  • Easy Mobility: Casters, which incorporate a high-grade nylon wheel with a die-cast aluminum frame, provide 360° rotation
  • Sturdy Construction: Made from extruded aluminum, the dynamometer table is lightweight, strong and corrosion-resistant
  • Leveling Jacks: When at rest and in operation, hand-operated leveling jacks, with rubber pads for vibration control, lift the casters from the floor to provide a solid foundation
  • Versatile: Its industry accepted T-slot extrusions accommodate standard fractional or metric fasteners allowing easy reconfiguration
  • Blower Mounting: To accommodate blowers required for brake cooling of certain HD/ED Dynamometers, tables are drilled and tapped for convenient blower mounting underneath the table top.
  • Built-in Shelf: For calibration beam, tools and accessories. Also used for mounting of TSC 401 Torque-Speed Conditioner and DES Power Supply (for tables ordered with WB/PB Series Dynamometers).

Custom Tables and Options

  • 19″ Rack Mounts: Can be added for dynamometer controllers, readouts, power analyzers and other supporting electronics
  • Table Height: Choose from 2 different working heights to allow testing from either a standing or seated position
  • Top Shelf: Fits over any standard dynamometer table and dynamometer (see photo below)
  • Locking Drawer: Ideal for a laptop computer
  • Built-in Cabinet: For storage of tools and accessories
  • Multiple Dynamometers: Up to 3 sets of mounting holes can be drilled and tapped to accommodate up to 3 dynamometers, depending on the model
  • Fixtures and Protective Covers: Can be added to any basic table at an additional cost. Some assembly required.

                    [post_content] => The Powder Brake Dynamometer (PB Series) contains, as its name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction. They are ideal for applications operating in the low to middle speed range or when operating in the middle to high torque range. Like Hysteresis Brakes, Powder Brakes provide full torque at zero speed. Like the Eddy-Current Brake Dynamometers, the PB series are water-cooled, allowing for power ratings up to 48 kW. The PB Dynamometers have accuracy ratings of ± 0.3% to 0.5% full scale, depending on size and system configuration.

Features

  • 9 Models with Maximum Torque from 5 N·m to 1 200 N·m (3.69 lb·ft to 885 lb·ft)
  • Braking Power: 500 W to 48 kW
  • Stable Braking Torque
  • Low Moment of Inertia
  • Operation in Either Rotational Direction
  • Braking Torque Measurement Integrated
  • Integrated Optical Speed Sensor
  • Special designs available upon request

Operating Principles

The PB Series - Powder Dynamometers contain, as their name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction between rotor and stator. The Powder Dynamometers (PB) produce their rated torque at zero speed. The element to be tested can be loaded at standstill to determine the starting torque. Optical Speed Sensor Each PB Series Dynamometer has a standard optical speed sensor. PB 43 has an optical speed sensor with a 30 PPR (Pulses Per Revolution); PB 65, PB 115 & PB 15 has an optical speed sensor with a 60 PPR. For higher speed resolution in low speed applications, Magtrol offers a 600 PPR or 6 000 PPR encoder as an option.

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). WB Series Dynamometers integrate a torque measuring system with accuracy ratings of ± 0.3 % to ± 0.5 % full scale, depending on size and system configuration.

Features

  • 12 Models with Maximum Torque from 400 mN·m to 560 N·m (56.6 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 (≤ 80 000)
  • 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 80 000 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 is equipped with an optical speed sensor. WB 32 is equipped with a 4 PPR (Pulses Per Revolution) encoder, WB 43 and WB 65 HS are equipped with a 30 PPR encoder; WB 65, WB 115 & WB 15 are equipped with a 60 PPR encoder.

These extremely versatile fixtures also enable easy motor centering for coupling to a Magtrol HD Series Hysteresis Dynamometer. (Couplings can be supplied upon request.) Various motor lengths are accommodated by either an attached T-slotted base plate or sliding base, depending on the model. The AMF-1, -2 and -3 Fixtures feature one or two adjustable bridges, each fitted with a fluted knob clamp screw, to allow clamping anywhere along the axis of the motor. The adjustable bridge on the AMF-V Fixture incorporates a straight-line action clamp with a V-angle rubber padded clamp to maximize the mounting area. To safeguard the motor, locking thumb screws provide protection against vibration and all motor-to-fixture contact surfaces are nylon padded for scratch-free clamping.

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
  • 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.
