General Instructions
This manual includes information on assembly and testing of DH and DS Motors.
To provide timely motor delivery when a customer places an order, you need to have all
the necessary modules and equipment on hand.
DH and DS motor assembly is based on a modular building concept. Each motor consists
of two modules; the housing module and the gear wheel set module. When assembled,
these two modules constitute a complete motor.
The variation in motor size (displacement) is determined by the gear wheel set module.
One housing module is common for all motors of a given flange type.
