Product Description
The ATK-25 is a unique shaft alignment solution, specially designed for small equipment. The ATK can be used to measure parallel and angular alignment, for correction of pitch, yaw, vertical, and horizontal positioning. It works in crowded or constrained locations where other tools will not fit.
Alignment is critical for rotating equipment. Poor alignment can cause:
- Excessive Vibration: Misaligned shafts lead to higher vibrations, which can result in mechanical failure or decreased performance
- Increased Wear and Tear: Bearings, seals, and couplings can experience premature wear due to the
additional forces exerted by misaligned shafts
- Equipment Failure: Continuous operation with misaligned shafts can lead to mechanical failure,
resulting in costly repairs and downtime
- Reduced Quality: In many industries, precision machinery is critical to maintaining product quality
Proper alignment tools and techniques provide major benefits, and are essential to achieving:
- Smooth operation, with the lowest noise and highest performance
- Long lifespan of component parts and minimum maintenance costs
- Reliable Operation, with the minimum downtime
- High production quality
Motor testing also requires good shaft alignment to produce the most accurate and consistent results. Unfortunately, the shaft alignment solutions widely available are not designed for use with smaller equipment.
Held on the V-block of one shaft, the ATK measures two tangent points on the target shaft. From those two measurements, angle can be determined from rise-over-run. Parallel position can be determined by measuring the target shaft on two sides, 180° opposite.
The ATK-25 includes attachments to accommodate a range of axial spacings between shaft ends. It includes a high-quality depth indicator, and is supplied in a durable, fitted case with all necessary tools.
Features
- Unique shaft alignment solution, specially designed for small equipment

- Measures parallel and angular alignment, for correction of pitch, yaw, vertical, and horizontal
positioning
- For shaft sizes: Ø5 … Ø25 mm (also suitable for Ø3/16 in … Ø1 in)
- User friendly design

[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). 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.

PT Series T-slot Base Plates are used for creating a basic test rig by mounting a Magtrol Dynamometer,
Brake or
Torque Transducer in line with the unit to be tested. Depending on the system configuration, a riser may be required to lift the transducer from the baseplate to the shaft height of the brake and/or the motor being tested. Magtrol RTM Riser Kits come complete with attachment hardware for the transducer and T‑nuts and bolts for attachment to the PT Base Plate.

[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.
