Permanent magnet stepper motors

Commercial series

The M series instrument stepper motors are high quality permanent

magnet types providing a choice of 18,15, 7.5 or 3.6 degree step angle.

The motors may be specified fitted with gearheads where increased

torque and resolution are required at reduced operating speed. The M

series motors offer excellent performance combined with low pricing.

They are ideally suited to instrumentation applications where large

production volumes are likely. A comprehensive programme of drives,

power supplies and controllers are available for the small volume user

to construct advanced single and multi-axis positioning systems.

note The above motors are 4 phase units suitable for use with uni-polar or bi-polar drive circuits with the exception

of the 15M029D-1B motor which is designed specifically for Bi-polar operation .

Bi-polar versions of the other motors in the range are available to special order.
