Introduction
The PASCO Model ME-8955 Rotational Motor Drive
was designed as an accessory to the Model ME-8951
Rotating Platform. The Rotational Motor Drive can be
used to drive experiments using the ME-8952 Centripetal Force Accessory, ME-8956 Coriolis Effect Accessory and ME-8957 Rotational Acceleration Tank. The
Rotational Motor Drive can be powered by a DC
Voltage Supply (SF-9582), a Function Generator (PI-
9598) or the Power Amplifier (CI-6552).
Equipment
The ME-8955 Rotational Motor Drive includes:
- Rotational Motor Drive assembly with 3-step
pulley and banana plugs for connection to a DC
voltage power supply.
- Pyrathane drive belt.
