Product name:permanent DC motor magnet
Size completed ring: 18mm OD x 14mm ID x 20mm Long
Material: Neodymium (NdFeB).
Grade: N45H
Coating: Nickel (Ni)
OD = Outer Diameter
ID = Inner Diameter
N45 equals very strong magnetic material. The "H" represents a high heat rating. Standard neodymium magnets - those with no extra letter after the number rating - will produce their maximum strength up to 176 degrees F. Beyond 176, standard NdFeB magnets begin to lose strength. These N45H magnets will maintain full strength up to 248 degrees F - perfect for applications which require high heat tolerance - such as some motors.
ASSEMBLY REQUIRED: These magnets will be sent as 8 arc segments -
4 with N Poles on the outer diameter and 4 with N Poles on the inner diameter.
PLEASE NOTE: As with ALL neodymium magnets, these arc segments are very fragile. Therefore, 2 extra arc segments will be included with each lot purchased - one of each polarity.
*** Please be careful when assembling.***
