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
- Works in crowded or constrained locations where other tools will not fit
- 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.

[post_content] => Magtrol Models 5500 and 5501 are manually-operated switch boxes that permit the connection of up to three Magtrol Dynamometers to a single
DSP7000 Dynamometer Controller. Use of the switch boxes facilitates quick and easy interfacing of multiple dynamometers without the necessity of disconnecting and reconnecting the brake and control cables. For Magtrol
WB Eddy-current or
PB Powder Brake Dynamometers, BOTH a 5500 AND a 5501 Switch Box are necessary. Magtrol
HD or ED Hysteresis Dynamometers only require the 5500.

[post_content] => DES 410 Series Power Supplies are specially designed for the full range of Magtrol’s
Eddy-current and
Powder brake dynamometers with the design goal providing the best response time. The DES 410 Series supplies are packaged in an industrial housing made of cast aluminum. This offers superior protection against radiated emissions in order to avoid any disruption of the surrounding electronics modules. This housing must be installed directly on the test bench, next to the brake, as close as possible.
The DES 410 Series supplies can be controlled by digital signals and analog set point coming from peripheral electronics. The DSP7010 Dynamometer Controller has been designed to work with the DES Series.
Control
The Power supply can be switched ON by remote control. The STAND-BY signal enables the output current to be delivered. This excitation current is controlled by a set-point in the 0-10 V DC range. The nominal value of the excitation current is set by internal resistors. There are two discrete outputs for alarms (open collector). The first is the "Temperature Alarm". It will indicate if the cooling water of the Dynamometer or the inner temperature of the DES 410 Series are out of limits. The second is the "Electrical Alarm". It occurs when an over current or a short circuit is detected. The output current is immediately turned OFF and latched while the General Alarm Relay is set under its Alarm position. A low state for 200 ms of the Stand-by signal resets the latch.
For applications with TANDEM dynanometers, the DES 410 Series units also control the power supply of the electromagnetic clutch.
Supply Voltage
The main supply voltage of the DES Series is in the 115/230 VAC - 50/60 Hz range. No selection is required.
The DES 410 power supply features a galvanic insulation between the main circuit and the dynamometer power.
The DES 411 does not have galvanic separation.
For safety reasons, the DES 410 Series case has to be grounded and the use of a ground fault current circuit breaker is recommended.
