Hyperion Motors

Z50 Data sheet

The new Z50 Series Hyperion Outrunners are big brothers to the excellent Z40 motor series, and share their quality in materials and design. From front to back, only the highest quality materials and components are used. The arrangement of twelve stator poles and fourteen magnet poles is primarily responsible for the high torque the Z50 Series generates on direct drive.
But there is much more to the "Z" than that. The stators are hand-wound in an optimal pattern for copper packing, so we get less resistance for a given number of turns. The stator plates are produced via a CNC process that insures uniformity, and made of the latest Japanese silicon steel with superior permeability at high induction, which makes the motors run more efficiently. The stator plates are finished with a lifetime anti-oxidant coating, to eliminate losses which can occur due to magnetic shorting from corrosion.

The magnets are especially made for the Z Series motors, and are rounded on both bell and stator sides. The result is that contact area with the bell is complete, and this has two benefits: First, heat transfer is maximized, so the magnets are much less subject to damage from overheating.

Second, the full contact with the bell on one side, and matching curvature to the stator on the other, means that the magnetic flux lines are complete and optimally shaped; this means higher efficiency, lower incidence of motor stalling, and smoother starts. The magnets themselves are produced in one of the foremost factories in the world, and are the latest type, featuring both an extremely high temperature rating and high magnetic strength. They are retained by fingers in the bell-end, and attached with a special high-temp glue. Finally, the high-speed, shielded stainless bearings in the Z50 Series are made by NMB Japan; expensive for Hyperion to install, but well worth it for smoothness and longevity.

One of the most important design features of the Z50 series is the large ring bearing which supports the rotating bell at the front of the motor (see pic above). During the development process on the Z40 series, we found that many failures of large OutRunner motors can be traced to deformation in the bell at higher rpm. By installing this ring bearing in the Z5025 to Z5045 motors, we fully support the bell both at front and back of the motor, and therefore greatly reduce the chances of magnet-adhesion failures.

The Hyperion Titan ESC (pictured above, right) are a perfect match for the motors:
TITAN-85HV-PO for Z5025
HP-TITAN-90HV-P0 for any Z50 on 10S/12S lithium
(HV ESC will have rating of 10S or 12S max, depending on version)

Use 4.0mm Gold bullet connectors for Motor<>ESC
We recommend 6mm Gold Barrel Connectors for Battery<>ESC connections

Use HP-Z50-FRTMNT, to mount the motor to firewall of the model. This mount is adjustable for a range of lengths, and includes a plate and bearing assembly which crosses behind the motor. The bearing fits to a small section of shaft at the back of the Z50 motor, made for this purpose.
The integrated 8mm steel shaft and propmount as seen on the motor is long enough to allow fitting most backplate-type spinners. We strongly recommend Hyperion ( #HP-LPRING-EP-S8 ) Precision 8mm Smooth adapter rings for use with APC "E" propellers, to insure a precise fit and less vibration.

Keep in mind that, with certain high-rpm battery/motor combinations, the Z50 motors are capable of over-driving "Electric" version props like APC "E" series. As such, you may consider using APC SPORT, APC PATTERN, or Wood props made for IC engines in that case. STAY BEHIND THE ROTATING PROP AT ALL TIMES!!

As general rules, most motor setups will produce 5000 to 7000 rpm, with a few choices up to 8500 rpm. Max allowed free rpm is 10,000, but in general a larger prop turning more slowly will yield best results.

Z50 MOTOR SPECIFICATIONS

Note: Suggested maximum prop sizes are on basis of using high-performance lithium packs such as Hyperion VX or CL series. These maintain very high voltage levels under load. Some other brands will deliver much less voltage, and therefore much lower current with the same prop. In all cases, it is your responsibility to measure peak current with a freshly charged battery pack, using ammeter such as Hyperion E-Meter, to be sure that the propeller and battery combination that you have chosen does not cause the motor to exceed the maximum current limits as given below, at your altitude. The prop maximums are given for "3D" and other highly aerobatic models where full throttle is rarely used, but maximum power required for short intervals. If your model is a sport or scale type, we recommend starting two inches smaller in diameter and perhaps reduce pitch, compared to these max prop sizes.

Z5025 Series

The Z5025 Series are appropriate for models in the Engine 90 to 120 class, in the weight range of 4.0~5.5Kg for aerobatic models. For slow-flying or scale models, weights may be in the range of 5.5Kg to 8.5kg.

Z5035 Series

The Z5035 Series are appropriate for models in the Engine 120 to 180 class, in the weight range of 5.0~6.5Kg for aerobatic models. For slow-flying or scale models, weights may be in the range of 6.5Kg to 10.0Kg.
