I have a Zapi Sem 0 controller labeled for 24 v. I want to control a 4hp series wound 24V dc motor. Is this possible and how do I connect to the controller?

Here are the specifics on the controller:

Technical details:
Supply voltage: 24 ÷ 36V
Maximum current: 150 ÷ 200A
High Frequency:16 kHz
Internal hour meter
Internal Battery Discharge Indicator (BDI)
Serial link
Complies with European CE Standards
Protection IP44
Dimensions: 140 x 120 x 85 mm

This controller has been developed for road traction and for trucks. It is suitable for electrical vehicles, equipped with D.C. Separately Excited Motor, from 0.5 kW to 2 kW. General features: MOSFET technology, microprocessor logic, faults memory, digital programming via console, regenerative braking.

Hi junser,

Most likely, no. Series and sepex motor fields are very different in the needed voltage and current. Either the controller would not work or fail. Or if it did work at all, the motor performance would suck big time due to weak field. I've used both series and sepex motors and controls (not Zapi). That's my opinion.

OK. I guess I need to make sure what type of motor I have. It has three terminals. Two terminals are close to the front of the motor and one at the rear. The negative wire is grounded to the case. The positve is connected to one of the terminals at the front of the motor. You jump the other terminal in front to the one in back. You can reverse the motor by swapping the terminal you connect the positive to and swap the jumper to the other terminal at the front.

Hi junser,

Looks like an automotive or truck winch motor. Bet it is series wound. Makes since for the connections you outlined.
