1. Safety instructions

• Do not exceed the maximum permissible op-

erating parameters (see Section 3 – Technical

data).

Long hair, loose clothing, or jewellery could get

caught and entangled in the rotating components.

• To prevent this danger, it is advisable to wear

a hairnet in the case of long hair.

• Do not wear unsuitable clothing or jewellery.

While operating with the belt pulley and the drive

belt, there is the additional danger that parts of the

body, e.g. fingers, may get pulled in or caught

between the belt and the pulley.

• Do not touch or hold any rotating components

of the experiment set-up.

The DC motor can also be used as a generator.

• In this state, do not connect any power supply

to the connectors.

2. Description

The DC motor is a small, compact motor with a

non-ferrous rotor and is used as an excitation unit

in experiments on mechanics, simple harmonic

oscillation and electricity. It can also be used as a

tachometer. Its low moment of inertia, in conjunc-

tion with a high starting torque, provides a short

acceleration time. Owing to the strong permanent

magnet of the stator, the motor is highly efficient.

The special brush and commutator arrangement,

in conjunction with friction bearings, guarantees a

long working life and low running noise.

The axle of the motor is equipped with a threaded

bush to which a pulley is attached by means of a

thread. This pulley allows other wheels and levers

to be attached to the axle for the excitation of

mechanical oscillations and waves.

The DC motor is attached to an angled supporting

bracket with stem. 4-mm connectors on the

bracket are responsible for supplying the equip-

ment with electricity as well as for tapping the

output voltage in generator mode.
