ABSTRACT:
An electric motor with attached tachogenerator wherein the tachogenerator may be attached to electric motors of varying types without significantly changing the housing or motor shaft bearing plate configuration and while maintaining the required environmental protection. The rpm signal generator of the tachogenerator is placed onto a motor shaft end portion which extends out of the motor housing through the shaft bearing plate and is enclosed by a closable housing accommodating a detector, e.g. a coil. The housing is latchable, for example by means of detent hooks, to the bearing plate or motor housing. The arrangement is particularly useful for electric motors where dust free and liquid tight protection is required.
