I don't post here myself, but having some background in this field i'd recommend you take this over to /r/NuclearPower. This seems a little out of scope. Hazmat and nuclear protection are generally different fields, sometimes they overlap however.
I'm more concerned as to why you're receiving motors that are possibly full of activated material yet you're asking strangers on the internet how to handle this stuff. If you're not considered a Nuclear Energy Worker (in Canada they call it this) you might actually not allowed to handle this stuff from a regulatory perspective depending on where you work/live. Now that looks like it's mostly copper and aluminium, so activation is less of a concern, but any part with steel in it could be a concern. It all depends on the amount of neutrons these things have seen.
Not knowing what they were used for I can't really give you any reasonable starting point. Maybe they just actuated water flow through a pipe in a reasonably safe area - maybe they were on a robot exploring a Fukushima Daiichi reactor core. The two are incredibly massive differences.
For a Geiger counter purchase, this looks nice:

At a minimum probably this:

Assuming you'll be handling these quite a bit, generally a starting point are placing film badge dosimeters outside the hot cell in an area that is considered 'not exposed', you don't want them outside though either as you get exposed to radiation from the environment as well. This is your control dosimeter. Depending how activated the materials in this motor are you might need a giant pile of lead bricks around it or just a thick concrete wall or both. Inside the hot cell, pick a specific spot that you place another film badge dosimeter at which is always a certain distance from where you store these things. The idea being is that radiation dose falls with distance, so to get consistent measurement keep the dosimeter a set distance away. You'll have to send those film badges away for analysis on a cycle set by your local regulatory agencies.
The facility I worked at which wasn't a nuclear power plant, for the office staff, if your annual dose was >2mSv/year compared to the control dosimeter then the technical staff were doing something wrong shielding wise. In Canada the effective dose limits for a nuclear energy worker is 50 mSv in any one year and 100 mSv in five consecutive years. The dose limit for pregnant workers is 4 mSv from the time the pregnancy is declared to the end of the term.
